In geometry, the truncated order-4 pentagonal tiling is a uniform tiling of the hyperbolic plane. It has Schläfli symbol of t_0,1{5,4}.

Uniform colorings

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.

Symmetry

There is only one subgroup of [5,5], [5,5]⁺, removing all the mirrors. This symmetry can be doubled to 542 symmetry by adding a bisecting mirror.
