non-Grünbaumian master:
sitphi  
general polytopal classes:
Wythoffian polychora  

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

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