Chamfered hecatonicosachoron

The chamfered hecatonicosachoron is a convex polychoron. It has 120 dodecahedra and 720 pentagonal bifrustums as cells. It can be obtained as the convex core of a hecatonicosachoron with hyperplanes passing under each pentagon face. It can also be made by truncating a joined hecatonicosachoron at 120 vertices of an inscribed hexacosichoron.

It is the convex core of several uniform polychora: garphi, pinpixhi, sophi, quipdohi.
