The template for the IH51 system is any quadrilateral with two opposite sides equal in length. All four sides can be shaped as indicated by the half-arrows. The template and any tile shape formed from it have no internal symmetry, as indicated by the dog pattern. An example of a template is
A translation cluster is
A section of the tiling formed by this template is shown below, with a translation cluster outlined. The two basic translations are indicated by the vectors drawn from the highlighted cluster. The tiling has two different centres of two-fold rotation symmetry and two different axes of glide reflection symmetry; an example of each is shown. The symmetry group of the tiling is pgg.
