The template for the IH36 system is a rhombus with angles of 60° and 120°. All four sides can be shaped, but all must be in the same way as indicated by the half-arrows. The template and any tile shape formed from it have an axis of internal reflection symmetry, as indicated by the dog pattern.
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 three-fold rotation symmetry, an axis of mirror symmetry and one of glide reflection symmetry; an example of each is shown. The symmetry group of the tiling is p31m.
