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

Vertex coordinates
Its vertices are in the same positions as those of its regiment colonel, the grand ditetrahedronary hexacosidishecatonicosachoron.
