Great ditetrahedrofissary dishecatonicosachoron

The great ditetrahedrofissary dishecatonicosachoron, or gadtifady, is a nonconvex fissary uniform polychoron that consists of 120 great icosidodecahedra and 120 great dodecicosidodecahedra. 6 great icosidodecahedra and 12 great dodecicosidodecahedra join at each vertex.

It is in the same regiment as the grand ditetrahedronary hexacosidishecatonicosachoron.

It is fissary with vertices coinciding by 3, and edges coinciding by two.
