Tetraapeirogonal tiling

In geometry, the tetrapeirogonal tiling is a uniform tiling of the hyperbolic plane with a Schläfli symbol of r{∞,4}.

Uniform constructions

There are 3 lower symmetry uniform construction, one with two colors of apeirogons, one with two colors of squares, and one with two colors of each:

Symmetry

(*∞42)
[∞,4]

(*∞33)
[∞,4,1+] = [(∞,3,3)]

(*∞∞2)
[1+,∞,4] = [∞,∞]

(*∞2∞2)
[1+,∞,4,1+]

Symmetry

The dual to this tiling represents the fundamental domains of *∞2∞2 symmetry group. The symmetry can be doubled by adding mirrors on either diagonal of the rhombic domains, creating *∞∞2 and *∞44 symmetry.
