Small dipentary hecatonicositrishecatonicosachoron

The small dipentary hecatonicositrishecatonicosachoron, or sidphithi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 120 great dodecahedra, 120 icosidodecadodecahedra, and 120 small dodecicosahedra. One small stellated dodecahedron, one great dodecahedron, five icosidodecadodecahedra, and five small dodecicosahedra join at each vertex.

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