Great rhombiprismic hecatonicosihecatonicosachoron

The great rhombiprismic hecatonicosihecatonicosachoron, or girphihy, is a nonconvex uniform polychoron that consists of 120 rhombicosahedra, 720 decagrammic prisms, and 120 great quasitruncated icosidodecahedra. One rhombicosahedron, two decagrammic prisms, and two great quasitruncated icosidodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the quasiprismatorhombated grand stellated hecatonicosachoron.
