Prismatohecatonicosintercepted hexacosihecatonicosachoron

The prismatohecatonicosintercepted hexacosihecatonicosachoron, or phinxhi, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 small rhombicosidodecahedra, 120 truncated dodecahedra, and 720 decagonal prisms. One octahedron, two small rhombicosidodecahedra, two truncated dodecahedra, and four decagonal prisms join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small rhombated hecatonicosachoron.
