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 regular tilings of the plane to be self-dual. It is also the 2D hypercubic honeycomb.

The square tiling is the honeycomb product of two apeirogons. It can also be seen as the result of stacking infinitely many apeirogonal prisms on top of each other.

The square tiling is also notable because it is equivalent to its own rectification and cantellation.

## Vertex coordinates

Coordinates for the vertices of a square tiling of edge length 1 are given by

• ${\displaystyle \left(i,\,j\right)}$,

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)
• xØx2xØx () (W2|W2 symmetry, as comb product of two apeirogons)
• s4o4o () (as alternated square tiling)
• o4s4o ()
• s4o4s ()
• s4x4o () (as additional alternated facetings)
• x4s4x ()
• s4x4s ()
• x4s4o ()
• s4s4x ()
• qo4oo4oq&#zx (as hull of two dual square tilings)
• qo4xx4oq&#zx (as hull of two opposite variant truncated square tilings)
