Tetraapeirogonal tiling
From HandWiki
In geometry, the tetraapeirogonal 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) [1+,∞,4] = [(∞,4,4)] |
(*∞∞2) [∞,4,1+] = [∞,∞] |
(*∞2∞2) [1+,∞,4,1+] |
---|---|---|---|---|
Coxeter | = | = | = | |
Schläfli | r{∞,4} | r{4,∞}1⁄2 | r{∞,4}1⁄2=rr{∞,∞} | r{∞,4}1⁄4 |

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.
