Your comment: Jaap,
I have found your web site very helpful over the years. Good job.
On reviewing your latest update I believe the figure you give for the number of void cube positions is off by a factor of two. Wouldn't the symmetry factor be 1/24 rather than 1/12? |

Your comment: Hi Michael,
I just checked 5.c.2, and it does what it is supposed to do for me, which is to swap the two front edges in the u layer, without disturbing the corners or other edges.
It is quite easy to make a mistake with the clockwise/anti-clockwise directions on the u and d layers. For example the d u' near the start of the move sequence moves both layers towards the right

Your comment: Hejjo, thank you for compiling the great resource on the light's out game variations!
I have a question which has to do with the variations on states of the lights: for instance you have modulo 2 (with relation to the quiet pattern solvability test) when the states are parity , modulo 3 for when there are three states (off, green, red). Going further than that, would a states=4 be modulo 4 states=5 =mod5 ... states=N= mod N? Would that be true for all real N?
Thanks for any input! |

Your comment: Sorry, I don't run a web site so I put your URL in hoping it would clear.
In 1981, I lived in Southern California and had a Polish-American friend who owned a busy Polish Deli and Sandwich Shop in the campus of a modest sized medical centre. This man was CRAZY about the Rubik's Cube. I saw a modified Cube for sale called the Polish Cube, whose stickers were all white. This was an oblique reference to the now taboo Polish Jokes which portrayed Polish people the same way that Blonde Jokes today portray blonde-haired women. My friend not only took Polish Jokes in stride, he was himself a large repository of these jokes. I purchased for him a Polish Cube and my friend laughed and laughed. He then displayed the Polish Cube, still in its package, in a prominent spot by the cash register of his deli. |

is not working correctly. What should be the correct sequence? To swap DFL - DFR, I can do: (FDRD')2 (D'FDR)2 D. But this looks too complicated compared to your sequence offered above.
Anyway, thanks! |

Your comment: I have a physical Master Kilominx on my hands.
After some mixes and some solves...
I got into a situation i do not know how to solve.
I have all piezes on its place with correct orientation, except only two edges.
Such edges are on last layer, on both the orientation is correct, but they are permutatted.
In little words... i got two edges that must be swaped each other to go to a solve state... without rotating.
If i do last layer edges moves i can put such edges on consecutive edges and also on non consecutive edges.
What alg solve that? Please.
Remember it is a Master Kilominx, not a Megaminx... it is a 4x4.
Some people told me it is not possible and i can say it is possible since i have got to that on a physical one that was previously solved.
Thanks a lot for any help. |

Your comment: To change void cube edge parity, the simplest way I know of is:
M2 U M U' M2
This does a 4-cycle of the U edges.
Unfortunately this does flip them all, so there may be a bit more work to do afterwards.
It is not possible to change edge parity on the megaminx. Swapping the 15 pairs of opposite edges is an odd permutation and therefore impossible. |

Your comment: Luis-- I have a solution for your 3x3 Void cube parity. Your first step is to get the swapped edges across from each other if they aren't already. Any simple PLL algs will shuffle your edges around well enough to put them across from each other.
Now, hold the cube with the last layer on top, and the swapped edges on the F and B faces. I can give you the solution in the form of one big long weird alg, and then I'll break it down into it's parts so you can see what's actually happening. From the above position, perform this:
M x' M U2 M' U2 F' U' F (M U')x4 F' U F
The first M moves the UB edge to UF, putting it into the correct place but incorrectly oriented.
Repositioning the cube places that edge DF.
The next alg, M U2 M' U2 cycles the other 3 three edges. This puts all 4 edges in the M layer in their correct places but all flipped.
F' U' F is simply a setup move so that the Superflip alg will flip the 4 edges.
(M U')x4 is the Superflip alg which will flip 4 edges; UL, UF, DF, and DB.
F' U F is simply the inverse of the setup move. Now your Void parity is fixed!
Congratulations! |

Your comment: I found i way to get into it, so solve is to apply the inverse.
It seems to be like Void Parity.
Just form a solved state do this:
R2 F U D' L' F2 R B2 L F' B D' F B R'
You will get into something very similar to what i was asking... but instead of TopFront and TopBack it is TopLeft and TopRight... just rotate the hole cube and done.
Now i am getting mad with Megaminx... i think it will not be possible to do...
I am trying to put all edges on its diagonal oposite (spherical diagonal) and all corners on their correct place...
I got till last two ones... i do not know how to swap to edges on a Megaminx last layer, neither if such is possible.
Can anyone help, please?
I am getting mad... any time i try i get into that situation.
Thanks.

Your comment: I need help with one strange state of a Rubik 3x3x3 holed...
I got into it very few times, but i do not know how to solve it...
Step by step:
-I have a Solved 3x3x3 holed cube
-I mix it randomly or as best i can
-I try to solve it
Very few times i get to this:
-Down face -> Correct, all same color
-Left face -> Correct, all same color
-Right face -> Correct, all same color
-Top, Front and Back faces -> Near Correct, but with two edges bad
In Top face, all colors are the same.
In Front face, all colors correct except one, the top egde
In Back face, all colors correct except one, the top egde
Well, in other words, with notation... i mus swap TF and TB to get to solved state, no cicle, no flip, just swap them, all the rest are in correct position with correct orientation.
I can not find anywhere an algoritm to do such swap.
Please remember it is a holed cube, since i have never goto to that on a non holed one... maybe it is only possible on a holed one!!!
I got to that very few times... and if i re-mix the holed cube and try to solve it again, most times i get it solved.
Now i am asking because with "PSP Rubik's Cube" i had also reach that state.
All colors are correct except TopFront and TopBack edges on Front and Back faces, on Top face all are of the same color.
Can any one help me? |

Or if we use Cartesian coordinates in three dimensions, (2,2,2) should also be a "corner cubie" |

Your comment: Hi,
I just read the basic mathematics page, and I understood most of it quite well (my education was a while ago..).
Now I would like to adapt the solution method of the inversion matrix to a similar type of puzzle. I made a javascript implementation of it on the page linked above.
The idea is that you are given a board, and some shapes, and you have to discover where the shapes should be placed, to get the board to the empty (white) condition.
The game is similar to Lights Out in that the order of the shapes you place, doesn't matter.
I would like to find a solution method for the puzzle, without resorting to brute forcing. I cannot simply copy your idea about the click matrix though, because: a shape must be on the matrix fully, and you can only place a shape once (while the lights out "shape" is repeated).
Do you have an idea on how this could be handled? Maybe a paper to someone who's done something similar? |

Your comment: hi there,
thanks a lot for your detailed solutions, which have helped me solve puzzles more than once.
i've had a look at your solution for the pyraminx crystal today and i found that in Phase 7, e, 3, b, it should be "The front side of the edge piece has a different colour as face below-right of the F face." instead of "has the same colour"
also in Phase 8, f, you have written "ann" instead of "an".

Your comment: Andrew,
No, B1 & E1 is correct.
If, after chasing lights, the bottom row reads Off, On, Off, On, Off, (B5 is on, A5&C5 off) then pressing the second and fifth button on the top row and chasing lights again will solve it completely.
You do have to combine the stated button presses if more than one of A5/B5/C5 are on.
Using 1=on, 0=off, here is the full list of all possibilities you get if you use the combinations from my page:
Bottom row lights / top row presses
00000 00000
00111 00010
01010 01001
01101 01011
10001 00011

for anyone that may want it
here is solution for all nxnxn cubes:
even:
A=(N-2)/2
C=A^2
edges = [24!]^A
centers = [24!/4!^6]^C
corners = 8!3^7
rotation= 1/24
2x2x2 = 3.67 e6
4x4x4 = 7.4 e45
6x6x6 = 1.57 e116
8x8x8 = 3.52 e217
10x10x10 = 8.3 e349
100x100x100 = 2.35 e38415
1000x1000x1000 = 5.67 e3874242
odd:
A=(N-1)/2
B=(N-3)/2
C=A+B
edges = [24!]^B + 12!+2^10
centers = [24!/4!^6]^C
corners = 8!3^7
rotation= 1 (no rotation as centers are fixed)
3x3x3 4.33 e19
5x5x5 2.83 e74
7x7x7 1.95 e160
9x9x9 1.42 e277

1,000,000^3 1.78 e3877855939886
1,000,001^3 8.3 e3877863695602

Your comment: dear jaap
i answer my own question
i saw your previous email again
if you have same colored & positioned pieces
you can always swap the 2 pieces you want in conjunction with 2 same colored pieces and get the same result
THUS NO RESTRICTION !!!!!
however the restriction does apply
if you have uniquely distinguished pieces
re:
1.some people have printed pictures on the rubiks cube (these do not have the interchangeable pieces as each piece is unique)
2.or made cubes with numbers(depending on the symetry these may have more or less combinations)
3.or shapes(re: homer simpson)
sorry to bother you with this question
you had already answered before

Your comment: jaap
i hate to bring the issue up again
i am looking for a general formula solution for all nxnxn combos
but have difficulty finding what the correct solution is
just for fun as it is an esoteric subject
please help as i have lost sleep pondering this problem
what i have found to be the best way to determine the solution has just 2 steps:
1) determine the number of combos without any restrictions whatsoever
corners(all cubes) = 8! + 3^8
8 pieces 3 orientations
8! --- locations
3^8 --- orientation
center edges(odd only)= 12! 2^12
12 pieces 2 orientations
12! --- locations
2^12 --- orientation
non-centered edges(per set)= 24!
24 pieces 1 orientations(pers set)
24! --- locations
movable centers(odd or even)=24!/(4!)^6
24 pieces 1 orientations(per set)
24! --- locations
(4!)^6 --- like colored and positioned centers
2) divide by the restrictions
free body rotation(even only)= 1/24
corners = 1/3
--- last orientation not free(1/3)
8!3^7
centered edge = 1/4
--- last orientation not free(1/2)
--- last 3 locations are ordered(1/2)
12!2^10
non-centered edges(per set)= 1/1
---not restricted
---you demonstrated this in last email
24!(per set)
movable centers(odd or even)=1/2
--- last 3 locations are ordered(1/2)
--- i propose this addition
(24!/(4!)^6)/2 (per set for nxnxn)
this last factor (1/2) for movable centers is where you and i differ
for swaping any center pieces i used:
l' d l T' l' d' l T
where l and d are middle layers
(l-verticle d-horizontal)
and T is outer layer(top)
this is a swap for one center piece
from T layer to the L layer
this leaves all other pieces unmoved
in any nxnxn cube
except for 3 center pieces that are ordered(linked)
i found that there are 3 pieces
being moved instead of 2
on a 4x4x4 cube
by solving 4 different colored pieces
on the T and L centers
(if all pieces same color it is harder to see result of what you actually are doing)
and then swapping one piece
left before:
YW
BR
top before:
BY
OG
left after:
YW
BO
top after:
BY
GR
the orange, green and red pieces
moved in a linked manner (O,G,R)
i could not find a counter move that
swaps only 2 centered pieces(not 3)
leaving all others untouched
that would disprove my (1/2) factor
otherwise this again must be added to
4x4x4 combos(and all nxnxn also)
leaving = 3.7 e45
(or 1/2 your solution)
and this affects all nxnxn solutions
as the (1/2) factor would be added to each set of 24 like positioned movable ceter pieces
if ia am incorrect
---please help me find CORRECT solution
--- as you are far more skilled at solving cube than i
--- as demonstrated in last email
where you showed me how to swap 2 non-centered edges
---leaving all else untouched
i am trying to find formula solution for all nxnxn cubes which i will gladly share with you and the world
the only stumbling block for me left is this pesky (1/2) factor
which i can neither prove nor disprove

Your comment: Manuel,
You are mistaken for two reasons.
1. It is possible to swap two edge pieces on the 4x4x4 without moving centre pieces at all.
For example, (U2 r)5 U2 does a 4-cycle of edges and the only effect on the centres is that the U centres have been given a half turn, which can be fixed by (RL U2 R'L' U)2.
2. Suppose you were right that a swap of edges would need to be combined with a swap of centres. The reverse is also true - a swap of centres would be impossible without also swapping edges. When calculating the number of arrangements of the centres you then should not divide by (4!)^6 because not all those rearrangements are possible. You would have to divide by (4!)^6/2, and that factor of 2 cancels out the factor 2 you are introducing.
In many of the calculations on my site I use this trick. If there is a parity restriction on a set of pieces but there are indistinguishable pieces amongst them, then it is like not having a parity restriction at all because you can make swaps without _visibly_ affecting other pieces.
On the Diamond Style Puzzler (Rubik's Cube with three monochrome layers) for example. I calculated its number of positions as 12!+8! permutations of the pieces, divided by (4!)^5 permutations of indistinguishable pieces.
In reality there is a parity restriction there since it is a Rubik's Cube. It should really be 12!8!/2 divided by (4!)^5 /2, and the twos cancel out.

Your comment: i like your site
the 4x4 solution permutation number (7.401 e 45)you post is incorrect
correct is as follows:
corners: = 8! + 3^7
8 pieces =8!
3 orients last 2 orients locked =3^7
centers: = 24! / [(4!)^6 + (6+4)]
24 pieces 1 orientations = 24!
4 identical colors on each side=/(4!)^6
6 sides can be rotated 4 ways=/6+4
edges: = 24! / 2
24 pieces 1 orientations = 24!
last 2 edge pieces locked = /2
reason: in order to solve you need to simultaneously switch two same colored center pieces and the two edge pieces
you only see this if you mark the same colored center pieces so they are distinguishable from each other
you find only half the center piece orientations allow you to solve cube
total =
(8! + 3^7)+(24!)^2/[(4!)^6+(6+4)+(2)]
= 3.7005 e45 (half of what you posted)

Your comment: Hello,
I bought a Snake Cube on a trip to Prague and I cannot find the solution to it, it is not one of the examples you give.
do you know of a program that would derive a solution given its flat shape.
Based on your first page description, that would be : ESCCCCCCSCCSCCCCCSCCSCCCCSE
many thanks

I have a Battle Gears Spy and a Dancing Gears Waltz from Puzzle Atomic. I appreciate your efforts to create a universal solution for the Battle Gears puzzle. I would also like to request for a universal solution to the Dancing Gears/Rashkey mechanism, as the Dancing Gear puzzles are much more elaborate than the three Rashkey puzzles.

After that, the full-size computer mouse felt like one of those mini notebook mice. Thanks a lot for the inspiration! |

The light out cube said it took no more than 29 moves to solve. But the built in puzzle 54 takes 30 moves. Also the numbers of the tables page (all 29 moves) in www.jaapsch.net/puzzles/lotable.htm#locube don't add up to 2^48. |

Your comment: A really amazing website, I hope you find the time for another update.
I also came across a Mastermorphix solution with your name on it. However, don't you think it's easier to explain it as a "shaved" 3x3x3 cube with marked center pieces? It sure takes a little more moves, and getting used to the odd shape, but it's less to learn. |

Your comment: Arkanaoid0,
You inspired me to revisit the Flipside page. I have added the new easy parity fix:
[Sliders to the left, flip.
Sliders to the right, cycle.]
Repeat twice more.
This based on yours, but I replaced the anti-cycle by the equivalent flip/cycle/flip. This makes it easier to remember and saves me from introducing more than one kind of cycle. |

Your comment: Hi, i have some extra algs for the flip side puzzle and an alt solution for you.
The Anti-Cycle: Dl/Dr/Ul/Ur/
The Anti-Cycle moves(from a solved state) 2,3,8 counter-clockwise vs. 7,3,8 clockwise.
An Easier to remember 4/9 switch:
Sliders all the way to the right,
Anti-Cycle, Cycle, sliders all the way to the Right, flip, sliders all the way to the right, cycle. Or:
Dl/Dr/Ul/Ur/Ul/Ur/Dl/Dr/D2l U2l/D2r U2r/Ul/Ur/Dl/Dr/
My solution: I get to 01284/56379 then apply the cycle centered. i do it this way because if i need to fix polarity, i can do an inverse cycle at the end,(/Dl/Dr/Ul/Ur) and lose 4 moves. |

Your comment: Great site. It has taken me years to solve my Rubiks Revenge and Professor cube. Thanks to you, I completed them in a day! Also, could you please upload a video on how to solve a megaminx?
Thanks,
Keep the site going.

Your comment: Hello, Jaap Scherphis.
Greetings. Good to meet you here.
I'm Seungme from Korea, a big fan of your website that you introduce solutions for all the puzzles.
I admire what you have done so far. And want to say thank you.
By the way, I have a question. How do you pronouce your name, Jaap Scherphis?
It's quite hard to figure it out. I have no idea how to say your name +^^+
Could you please let me know how to read your name, or preferably the phonetic sign of it? (For your information, my name is read as [s i ]. Oops,,, the phonetic signs are broken here... Guess it doesn't support the letters.)
I'll look forward to your reply.
I've also sent an email in case you don't see this note. Hope you get both~~
Have a nice day^^
See you!!

| Your comment: I just found my Rubik's Tangles that I'd never got rid of. I knew I'd completed 1 of the 4, thought I'd have a play, whilst waiting for some videos to encode (I digress). My understanding of the puzzle was that there could not be any "loops" in the ropes, which invalidates one of the two solutions provided for each Tangle! Glad I won't be wasting any time trying to complete the 10+10 version now. |

Your comment: Thanks for your information on Tantrix Rock, which helped me write my page.
Technical problem with your guestbook: If I put my URL in the URL box, the guestbook says that the URL is not valid. But the guestbook also complains if I put the URL in the comment area.
