Small dipentary prismatotrishecatonicosachoron

The small dipentary prismatotrishecatonicosachoron, or sidpipthi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 1200 triangular prisms, 120 rhombicosahedra, and 120 small icosicosidodecahedra. One small stellated dodecahedron, five triangular prisms, five rhombicosahedra, and five small icosicosidodecahedra join at each vertex.

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