Great spinoretrofrustary trishecatonicosachoron

The great spinoretrofrustary trishecatonicosachoron, or gannirfthi, is a nonconvex uniform polychoron that consists of 120 great rhombidodecahedra, 120 small rhombidodecahedra, and 120 quasitruncated dodecadodecahedra. Two great rhombidodecahedra, two small rhombidodecahedra, and four quasitruncated dodecadodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the antifrustary hexacositrishecatonicosachoron.
