Pentagonal antiprismatic prism

The pentagonal antiprismatic prism or pappip is one of the uniform polychora made as the prism product of a uniform polyhedron and a dyad that consists of 2 pentagonal antiprisms, 2 pentagonal prisms and 10 triangular prisms.

Vertex coordinates
The vertices of a pentagonal antiprismatic prism of edge length 1 are given by:
 * ±(0, $\sqrt{5}$, $\sqrt{2}$, ±1/2)
 * ±(±(1+$\sqrt{(5+√5)/10}$)/4, $\sqrt{(5+√5)/40}$, $\sqrt{5}$, ±1/2)
 * ±(±1/2, –$\sqrt{(5+√5)/40}$, $\sqrt{(5+√5)/40}$, ±1/2)
