Small dipentary hecatonicosihexacosiprismatotrishecatonicosachoron

The small dipentary hecatonicosihexacosiprismatotrishecatonicosachoron, or sidphixipthi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 120 great dodecahedra, 1200 triangular prisms, 600 truncated tetrahedra, 120 small rhombicosidodecahedra, and 120 small icosicosidodecahedra. One small stellated dodecahedron, one great dodecahedron, five triangular prisms, five truncated tetrahedra, five small rhombicosidodecahedra, and five small icosicosidodecahedra join at each vertex.

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