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 name suggests, it can be obtained by cantitruncating the grand hexacosichoron.
The vertices of a great rhombated grand hexacosichoron of edge length 1 are given by all permutations of:
