Small dipentary disprismatohecatonicosidishecatonicosachoron

The small dipentary disprismatohecatonicosidishecatonicosachoron, or sidpadiphdy, is a nonconvex uniform polychoron that consists of 120 great dodecahedra, 720 pentagrammic prisms, 1200 triangular prisms, 120 truncated icosahedra, and 120 small icosicosidodecahedra. One great dodecahedron, five pentagrammic prisms, five triangular prisms, five truncated icosahedra, and five small icosicosidodecahedra join at each vertex.

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