Quasiprismatohecatonicosachoron

The quasiprismatohecatonicosachoron, or quiphi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra and 720 pentagrammic prisms. 2 small stellated dodecahedra and 10 pentagrammic prisms join at each vertex.

It is in the same regiment as the rectified great faceted hexacosichoron.

A double cover of this polychoron can be formed by pushing the cells of the grand stellated hecatonicosachoron inward.
