Small snub dodecahedron

The small snub dodecahedron, sassid, or compound of six pentagrammic antiprisms is a uniform polyhedron compound. It consists of 60 triangles and 12 pentagrams, with one pentagram and three triangles joining at a vertex.

Its quotient prismatic equivalent is the pentagrammic antiprismatic hexateroorthowedge, which is eight-dimensional.

Vertex coordinates
The vertices of a small snub dodecahedron of edge length 1 are given by all even permutations and even sign changes of:
 * (±$\sqrt{5}$, ±$\sqrt{(15+√5)/40}$, ±$\sqrt{5√5}$/10)
 * (±$\sqrt{5}$, ±$\sqrt{(5–2√5)/3}$, ±$\sqrt{(√5+√5(√5–2))/20}$/10)
