Retrosnub square tiling

The retrosnub square tiling, or rasisquat, is a non-convex uniform tiling of the Euclidean plane. 3 triangles and 2 squares (seen as 4/3-gons) join at each vertex of this tiling. It can be formed by alternation of the quasitruncated square tiling, followed by adjustment of edge lengths to be all equal.

Representations
A retrosnub square tiling has the following Coxeter diagrams:

s4/3s4/3s (half symmetry)
 * s4/3s4o (full symmetry)
