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