In geometry, the infinite-order square tiling is a regular tiling of the hyperbolic plane. It has Schläfli symbol of {4,∞}. All vertices are ideal, located at "infinity", seen on the boundary of the Poincaré hyperbolic disk projection.

Uniform colorings

There is a half symmetry form, , seen with alternating colors:

This tiling represents the mirror lines of *∞∞∞∞ symmetry. The dual to this tiling defines the fundamental domains of (*2^∞) orbifold symmetry.

This tiling is topologically related as a part of sequence of regular polyhedra and tilings with vertex figure (4ⁿ).
