Small ditrigonal hecatonicosiprismatodishecatonicosachoron

The small ditrigonal hecatonicosiprismatodishecatonicosachoron, or sid thipady, is a nonconvex uniform polychoron that consists of 720 pentagrammic prisms, 120 quasitruncated great stellated dodecahedra, 120 small ditrigonal dodecicosidodecahedra, and 120 quasitruncated dodecadodecahedra. 1 pentagrammic prism, 1 quasitruncated great stellated dodecahedron, 1 small ditrigonal dodecicosidodecahedron, and 2 quasitruncated dodecadodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small hecatonicosiprismatodishecatonicosachoron.
