As abstract polytope querco is isomorphic to sirco, thereby replacing retrograde triangles by prograde ones. – As such querco is a lieutenant.

Just as sirco allows for a gyrated stack, esquigybcu (J37), this quasi-version too has an according gyrated stacking: rasquacu + inv stop + gyro rasquacu = gyquerco. In fact, both have the same vertex figure all over. But querco features full cubical symmetry, while gyquerco features 4-fold antiprismatic symmetry only, thereby dividing the according vertex set into 2 classes. As such gyquerco then would be the quasi-variant of esquigybcu.

This polyhedron is an edge-faceting of the great cubicuboctahedron (gocco).
