As abstract polytope gosid is isomorphic to snid, gisid, and girsid, thereby replacing prograde icosahedral triangles and (prograde) pentagrams respectively by prograde icosahedral triangles and pentagons, by prograde icosahedral triangles and retrograde pentagrams, by retrrograde icosahedral triangles and retrograde pentagrams.
