As abstract polytope qrid is isomorphic to srid, thereby replacing retrograde pentagrams by prograde pentagons. – As such qrid is a lieutenant.

Just as the lunes of srid had been reused in bilbiro and thawro, the more folded lunes of this conjugate polyhedron are being reused in their conjugates as well, i.e. in gibil biro and githawro.

This polyhedron is an edge-faceting of the great dodekicosidodecahedron (gaddid).
