As abstract polytope sroh is isomorphic to groh, thereby replacing octagons by octagrams.
This polyhedron could be thought of as the blend of 3 mutually perpendicular op, blending out those squares at intersection axes.
The small rhombihexahedron is an edge-faceting of the small rhombicuboctahedron (sirco).
The below provided matrix looks like both edge types would be alike. And in fact at each of them a square adjoins an octagon. However some are situated at a pseudo triangle (triangular hole), while the others are situated at a psuedo square (square hole). I.e. although the according symmetry equivalence classes behave alike the individual members within the full 0-1 matrix would behave differently. And therefore those remain different too within the according abstract polyhedron.
