* The regiment of gidrid contains that of gisdid and of oct.

This polyhedron allows for a chiral colored representation wrt. its purely rotational subgroup. That one then is gidrikid, the great dirhombichiricosadodecahedron. Triangles and pentagrams then fall into 2 subclasses each. Squares however, because of being hemihedral (running through the body center), remain the same.
