Invertifrustary prismatohexacosipentishecatonicosachoron

The invertifrustary prismatohexacosipentishecatonicosachoron, or ifpixophi, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra, 600 octahedra, 120 great dodecicosidodecahedra, 120 great icosicosidodecahedra, 120 small rhombidodecahedra, 120 icosidodecatruncated icosidodecahedra, and 1200 hexagonal prisms. One dodecadodecahedron, one octahedron, two great dodecicosidodecahedra, two great icosicosidodecahedra, two small rhombidodecahedra, four icosidodecatruncated icosidodecahedra, and four hexagonal prisms join at each vertex.
