The medial hecatonicosintercepted hecatonicosachoron, or mohiny, is a nonconvex uniform polychoron that consists of 120 dodecadodecahedra and 120 truncated great icosahedra. 3 dodecadodecahedra and 6 truncated great icosahedra join at each vertex.

It is wild because it has dodecadodecahedra intercepted by hexagons.
