Small rhombiprismic hecatonicosihecatonicosachoron

The small rhombiprismic hecatonicosihecatonicosachoron, or sirphihy, is a nonconvex uniform polychoron that consists of 120 rhombicosahedra, 720 decagonal prisms, and 120 great rhombicosidodecahedra. One rhombicosahedron, two decagonal prisms, and two great rhombicosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the prismatorhombated great hecatonicosachoron.
