Great prismatohecatonicosidishecatonicosachoron

The great prismatohecatonicosidishecatonicosachoron, or giphidy, is a nonconvex uniform polychoron that consists of 720 pentagrammic prisms, 120 quasitruncated small stellated dodecahedra, 120 icosidodecadodecahedra, and 120 great quasitruncated icosidodecahedra. 1 pentagrammic prism, 1 quasitruncated small stellated dodecahedron, 1 icosidodecadodecahedron, and 2 great quasitruncated icosidodecahedra join at each vertex.

It is in the same regiment as the quasiprismatorhombated grand stellated hecatonicosachoron.
