Small dipentary hexacosiprismatotetrishecatonicosachoron

The small dipentary hexacosiprismatotetrishecatonicosachoron, or siddip xupthi, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 great dodecahedra, 1200 triangular prisms, 600 truncated tetrahedra, 120 rhombidodecadodecahedra, and 120 small icosicosidodecahedra. One great icosahedron, one great dodecahedron, five triangular prisms, five truncated tetrahedra, five rhombidodecadodecahedra, and five small icosicosidodecahedra join at each vertex.

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