Great ditetrahedronary dishecatonicosachoron

The great ditetrahedronary dishecatonicosachoron, or giddatady, is a nonconvex uniform polychoron that consists of 120 regular dodecahedra and 120 great ditrigonary icosidodecahedra. 4 great ditrigonary icosidodecahedra and 4 dodecahedra join at each vertex.

It is in the same regiment as the ditetrahedronary dishecatonicosachoron.
