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.

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