Trishecatonicosachoron

The trishecatonicosachoron, or tahi, is a nonconvex uniform polychoron that consists of 120 regular dodecahedra, 120 great stellated dodecahedra, and 120 icosidodecadodecahedra. 1 dodecahedron, 1 great stellated dodecahedron, and 3 icosidodecadodecahedra join at each vertex.

It is in the same regiment as the small disprismatodishecatonicosachoron.
