Great dipentary dishecatonicosidishexacosichoron

The great dipentary dishecatonicosidishexacosichoron, or gidpid hiddix, is a nonconvex uniform polychoron that consists of 120 icosahedra, 600 truncated tetrahedra, 600 cubohemioctahedra, and 120 great rhombidodecahedra. One icosahedron, five truncated tetrahedra, five cubohemioctahedra, and five great rhombidodecahedra join at each vertex.

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