gitphi  

Looks like a compound of 2 great tripesic hecatonicosachora (gitphi), and indeed vertices coincide by 6, all other elements by 2.

As abstract polytope 2gitphi is isomorphic to 2sitphi, thereby replacing the decagrams by decagons and pentagons by pentagrams, resp. replacing quit sissid by tigid.
