Quasirhombated great grand stellated hecatonicosachoron

The quasirhombated great grand stellated hecatonicoscahoron, or qrigogishi, is a nonconvex uniform polychoron that consists of 600 regular octahedra, 1200 triangular prisms, and 120 quasirhombicosidodecahedra. 1 octahedron, 2 triangular prisms, and 2 quasirhombicosidodecahedra join at each vertex. It can be obtained by quasicantellating the great grand stellated hecatonicosachoron.

It is in the same regiment as the great sphenoverted hexacosidishecatonicosachoron.
