|Abstract & topological properties|
It is the only one of the 11 regular and uniform convex tilings of the plane to not be derivable from the regulars by truncation operations or alternation. It can be thought of as being constructed from the triangular tiling with layers of squares being inserted between adjacent layers of triangles. It can also be considered a blend of infinitely many apeirogonal antiprisms and apeirogonal prisms.
