Rectified grand hexacosichoron

The rectified grand hexacosichoron, or raggix, is a nonconvex uniform polychoron that consists of 600 regular octahedra and 120 great icosahedra. Two great icosahedra and 5 octahedra join at each pentagrammic prismatic vertex. As the name suggests, it can be obtained by rectifying the grand hexacosichoron.
