The trihexagonal tiling, or that, is one of the eleven convex uniform tilings of the Euclidean plane. 2 hexagons and 2 triangles join at each vertex of this tiling. It can be formed from the rectification of either the triangular tiling or its dual hexagonal tiling.

Vertex coordinates[edit | edit source]

The vertices of a trihexagonal tiling of edge length 1 are given by:

  • ,
  • ,

where i  and j  range over the integers.

Representations[edit | edit source]

A trihexagonal tiling has the following Coxeter diagrams:

  • o6x3o () (full symmetry)
  • x3x3o3*a () (P3 symmetry, triangles of two types)
  • s6x3o () (as alternated faceting)
  • s6o3x ()

Related tilings[edit | edit source]

The trihexagonal tiling is the colonel of a three-member regiment that also includes the triangular-hemiapeirogonal tiling and the hexagonal-hemiapeirogonal tiling.
