Square tiling

The square tiling, or squat, is one of the three regular tilings of the Euclidean plane. 4 squares join at each vertex of this tiling. It is the only one of the three regular tilings to be self-dual. It is also the 2D hypercubic honeycomb.

Vertex coordinates
Coordinates for the vertices of a square tiling of edge length 1 are given by where i and j range over the integers.

Representations
A square tiling has the following Coxeter diagrams:


 * x4o4o (regular)
 * o4x4o (as rectified square tiling)
 * x4o4x (as small rhombated square tiling)
 * x∞o x∞o (W2×W2 symmetry, as apeirogonal duoprism)
 * x∞x x∞o
 * x∞x x∞x)
 * s4o4o (as alternated square tiling)
 * o4s4o
 * s4o4s
 * s4x4o (as additional alternated facetings)
 * x4s4x
 * s4x4s
 * x4s4o
 * s4s4x
