Truncated order-4 pentagonal tiling

In geometry, the truncated order-4 pentagonal tiling is a uniform tiling of the hyperbolic plane.

A half symmetry [1+,4,5] = [5,5] coloring can be constructed with two colors of decagons.

This coloring is called a truncated pentapentagonal tiling.

There is only one subgroup of [5,5], [5,5]+, removing all the mirrors.
