Squat also can be seen as an extension of the general (n-gonal, apeirogonal) duoprism (n → ∞), thereby becoming a flat tiling.

The body-centered square tiling would be a (smaller) square tiling in turn.

There exist regular modwraps of this tiling, x4o4o|xRo, obtained by identifying every R-th vertex on each hole. These then allow representations as finite regular skew polyhedra, which happen to be the torical facial subsets, built by the lacing squares of the R-prismatic cells, of the (R,R)-duoprism.
