tiling of the hyperbolic plane. It has Schläfli symbol of , which means it has countably infinitely many apeirogons around all its ideal vertices.


Symmetry

This tiling represents the fundamental domains of *∞∞ symmetry.


Uniform colorings

This tiling can also be alternately colored in the ∞,∞,∞)symmetry from 3 generator positions.


Related polyhedra and tiling

The union of this tiling and its dual can be seen as orthogonal red and blue lines here, and combined define the lines of a *2∞2∞ fundamental domain. : : a or = ∪
