2sishi+2paphicki (?) clearly is an edge-faceting of the small stellated hecatonicosachoron (sishi). Thus the vertices coincide by 12 each, further edges coincide by 6, pentagrams by 4, and all other elements by pairs.

As abstract polytope 2sishi+2paphicki is isomorphic to 2gaghi+2paphacki, thereby replacing pentagrams by pentagons, resp. replacing sissid by gad, and stip by pip.
