IH36

 


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.
 

As an example, the following shaped tile can be made

        

Tiles of three different colours are required to avoid adjacent tiles of the same colour.
