Small dipentary dishecatonicosiprismatotrishecatonicosachoron

The small dipentary dishecatonicosiprismatotrishecatonicosachoron, or sidpid hipthi, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 icosahedra, 720 pentagrammic prisms, 120 truncated icosahedra, 120 small rhombicosidodecahedra, and 120 small icosicosidodecahedra. One great icosahedron, one icosahedron, five pentagrammic prisms, five truncated icosahedra, 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.
