Small rhombic trishecatonicosachoron

The small rhombic trishecatonicosachoron, or srithi, is a nonconvex uniform polychoron that consists of 120 small rhombidodecahedra, 120 great quasitruncated icosidodecahedra, and 120 icosidodecatruncated icosidodecahedra. One small rhombidodecahedron, two great quasitruncated icosidodecahedra, and two icosidodecatruncated icosidodecahedra join at each vertex.

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