The retroinverted prismatohecatonicosachoron is an edge-faceting of the rectified great faceted hexacosichoron (rigfix). In fact it can be seen as reduced( x3o3/2x5/2o , by 2thah ).

As abstract polytope ripahi is isomorphic to frox, thereby replacing pentagrams by pentagons, resp. by replacing gid by id and replacing stip by pip.
