Great rhombiprismic dishecatonicosachoron

The great rhombiprismic dishecatonicosachoron, or gripady, is a nonconvex uniform polychoron that consists of 120 great rhombidodecahedra, 120 great quasitruncated icosidodecahedra, and 1200 hexagonal prisms. One great rhombidodecahedron, two great quasitruncated icosidodecahedra, and two hexagonal prisms join at each vertex.

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