Trioctagonal tiling

The trioctagonal tiling or toct is a uniform tiling of the hyperbolic plane. 2 octagons and 2 triangles join at each vertex. It can be formed from the rectification of either the octagonal tiling or its dual order-8 triangular tiling.

Representations
A trioctagonal tiling has the following Coxeter diagrams:


 * o8x3o (full symmetry)
 * x3o3x4*a (half symmetry)
