Small stellated dodecahedral prism

The small stellated dodecahedral prism or sissiddip is a prismatic uniform polychoron that consists of 2 small stellated dodecahedra and 12 pentagrammic prisms. Each vertex joins 1 small stellated dodecahedron and 5 pentagrammic prisms. As the name suggests, it is a prism based on the small stellated dodecahedron.

Vertex coordinates
The vertices of a small stellated dodecahedral prism of edge length 1 are given by all even permutations of the first three coordinates of:
 * $$\left(0,\,±\frac12,\,±\frac{\sqrt5-1}{4},\,±\frac12\right).$$
