Great retrofrustary prismatohexacositetrishecatonicosachoron

The great retrofrustary prismatohexacositetrishecatonicosachoron, or girf puxthi, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 great rhombidodecahedra, 120 great ditrigonal dodecicosidodecahedra, 120 small icosicosidodecahedra, and 1200 hexagonal prisms. One dodecadodecahedron, one octahedron, two great rhombidodecahedra, two great ditrigonal dodecicosidodecahedra, two small icosicosidodecahedra, and four hexagonal prisms join at each vertex.

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