Great sphenofrustary trishecatonicosachoron

The great sphenofrustary trishecatonicosachoron, or gwifthi, is a nonconvex uniform polychoron that consists of 120 great ditrigonal dodecicosidodecahedra, 120 small dodecicosidodecahedra, and 120 quasitruncated dodecadodecahedra. Two great ditrigonal dodecicosidodecahedra, two small dodecicosidodecahedra, and four quasitruncated dodecadodecahedra join at each vertex.

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