Snub square antiprismatic honeycomb

A snub square antiprismatic honeycomb can be constructed by alternation of the truncated square prismatic honeycomb, although it can not be made uniform, but it can be given Coxeter diagram: and has symmetry ,4,2,∞sup>+. It makes square antiprisms from the octagonal prisms, tetrahedra (as tetragonal disphenoids) from the
