Small based dipentary hecatonicosiprismatohexacosidishecatonicosachoron

The small based dipentary hecatonicosiprismatohexacosidishecatonicosachoron, or sibdiphip xady, is a nonconvex uniform polychoron that consists of 120 icosahedra, 600 truncated tetrahedra, 120 truncated icosahedra, 1200 triangular prisms, and 120 small rhombicosidodecahedra. One icosahedron, five truncated tetrahedra, five truncated icosahedra, five triangular prisms, and five small rhombicosidodecahedra join at each vertex.

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