Truncated grand hexacosichoron

The truncated grand hexacosichoron, or taggix, is a nonconvex uniform polychoron that consists of 120 great icosahedra and 600 truncated tetrahedra. 1 great icosahedron and five truncated tetrahedra join at each vertex. As the name suggests, it can be obtained by truncating the grand hexacosichoron.

It is in the same regiment as the truncated great faceted hexacosichoron.
