Small hexacosidishecatonicosachoron

The small hexacosidishecatonicosachoron, or sixady, is a nonconvex uniform polychoron that consists of 120 truncated dodecahedra, 120 small dodecicosahedra, and 600 truncated tetrahedra. Two truncated dodecahedra, two small dodecicosahedra, and two truncated tetrahedra join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small sphenoverted hexacosidishecatonicosachoron.
