This Grünbaumian polychoron is an edge-faceting of the quasirhombated great grand stellated hecatonicosachoron (qrigogishi). It can be seen as a union of gipriphi plus the 600 pseudo-thah filled in as doubled up copies, in fact, these double-covers unite as 2thah, thereby letting the surface cross over at this former pseudo-cells. And indeed, the vertex figure is an asymmetric faceting of the vertex figure of qrahi. Therefore there can be blended 2 mirror symmetric such, and, correspondingly, the vertices of this polychoron coincide by pairs.

As abstract polytope gipriphi+600 2thah is isomorphic to spriphi+600 2thah, thereby replacing decagrams by decagons, resp. by replacing quit gissid by tid and replacing stiddip by dip.
