Small capped dipentary hecatonicosiprismatohexacosidishecatonicosachoron

The small capped dipentary hecatonicosiprismatohexacosidishecatonicosachoron, or sicdiphip xady, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra, 600 truncated tetrahedra, 120 truncated icosahedra, 720 pentagrammic prisms, and 120 small rhombicosidodecahedra. One small stellated dodecahedron, five truncated tetrahedra, five truncated icosahedra, five pentagrammic prisms, and five small rhombicosidodecahedra join at each vertex.

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