Octagonal tiling

The order-3 octagonal tiling, or just octagonal tiling, is a regular tiling of the hyperbolic plane. 3 octagons join at each vertex.

Representations
The order-8 triangular tiling has the following Coxeter diagrams:


 * x8o3o (main symmetry)
 * o8x4x (as truncated order-8 square tiling)
 * x4x4x4*a (octagons of three types)
