Great dishecatonicosachoron

The great dishecatonicosachoron, or gidahi, is a nonconvex uniform polychoron that consists of 120 great dodecicosahedra and 120 great quasitruncated icosidodecahedra. Two great dodecicosahedra and four great quasitruncated icosidodecahedra join at each vertex.

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