Small polar facetopental trishecatonicosachoron

The small polar facetopental trishecatonicosachoron, or sliffipathi, is a nonconvex uniform polychoron that consists of 120 great icosicosidodecahedra, 120 great icosidodecahedra, and 120 quasitruncated small stellated dodecahedra. Ten great icosicosidodecahedra, five great icosidodecahedra, and ten quasitruncated small stellated dodecahedra join at each vertex.

It also has small complex icosidodecahedra as pseudofacets.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the rectified great stellated hecatonicosachoron.
