Alternated order-4 hexagonal tiling

In geometry, the alternated order-4 hexagonal tiling is a uniform tiling of the hyperbolic plane. It has Schläfli symbol of (3,4,4), h{6,4}, and hr{6,6}.

Uniform constructions

There are four uniform constructions, with some of lower ones which can be seen with two colors of triangles:

*443	3333	*3232	3*22
