Great rhombated grand hexacosichoron

The great rhombated grand hexacosichoron, or graggix, is a nonconvex uniform polychoron that consists of 720 pentagrammic prisms, 600 truncated octahedra, and 120 truncated great icosahedra. 1 pentagrammic prism, 1 truncated great icosahedron, and 2 truncated octahedra join at each vertex. As the names suggests, it can be obtained by cantitruncating the grand hexacoscichoron.
