In geometry, the truncated tetrapentagonal tiling is a uniform tiling of the hyperbolic plane. It has Schläfli symbol of t_0,1,2{4,5} or tr{4,5}.

Symmetry

There are four small index subgroup constructed from by mirror removal and alternation. In these images fundamental domains are alternately colored black and white, and mirrors exist on the boundaries between colors.

A radical subgroup is constructed , index 10, as , (5*2) with gyration points removed, becoming orbifold (*22222), and its direct subgroup , index 20, becomes orbifold (22222).
