Order-4 square tiling honeycomb Order-4 square tiling honeycomb In the geometry of hyperbolic 3-space, the order-4 square tiling honeycomb, is one of 11 paracompact regular honeycombs. It is called "paracompact" because it has infinite cells and vertex figures, with all vertices as ideal points at infinity. Given by Schläfli symbol {4,4,4}, has four square tilings, {4,4} around each edge, and infinite square tilings around each vertex in an square tiling {4,4} vertex arrangement. It has many reflective symmetry constructions, as a regular honeycomb, ↔ with alternate types (colors) of square tilings, and with 3 types (colors) of square tilings, with a ratio of 2:1:1.
