Rhombic small hexacosihecatonicosachoron

The rhombic small hexacosihecatonicosachoron, or rassixhi, is a nonconvex uniform polychoron that consists of 120 truncated icosahedra, 600 cubohemioctahedra, and 720 pentagonal prisms. Two truncated icosahedra, two cubohemioctahedra, and two pentagonal prisms join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small rhombated hexacosichoron.
