Great hecatonicosihexacosihecatonicosachoron

The great hecatonicosihexacosihecatonicosachoron, or ghixhi, is a nonconvex uniform polychoron that consists of 120 quasitruncated great stellated dodecahedra, 120 great dodecicosahedra, and 600 truncated tetrahedra. Two quasitruncated great stellated dodecahedra, two great dodecicosahedra, and two truncated tetrahedra join at each vertex.

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