Square-hexagonal antiprismatic duoprism

The square-hexagonal antiprismatic duoprism or squahap is a convex uniform duoprism that consists of 4 hexagonal antiprismatic prisms, 2 square-hexagonal duoprisms and 12 triangular-square duoprisms.

Vertex coordinates
The vertices of a square-hexagonal antiprismatic duoprism of edge length 1 are given by:
 * (±1/2, ±1/2, 0, ±1, $\sqrt{5+√3}$/2)
 * (±1/2, ±1/2, ±$\sqrt{{{radic|3}}-1}$/2, ±1/2, $\sqrt{3}$/2)
 * (±1/2, ±1/2, ±1, 0, -$\sqrt{{{radic|3}}-1}$/2)
 * (±1/2, ±1/2, ±1/2, ±$\sqrt{{{radic|3}}-1}$/2, -$\sqrt{3}$/2)
