Rectification wrt. a non-regular polytope is meant to be the singular instance of truncations on all vertices at such a depth that the hyperplane intersections on the former edges will coincide (provided such a choice exists). Within the specific case of srid as a pre-image these intersection points might differ on its 2 edge types. Therefore srid cannot be rectified (within this stronger sense). Nonetheless the Conway operator of ambification (chosing the former edge centers generally) clearly is applicable. This would result in 2 different edge sizes in the outcome polyhedron. That one here is scaled such so that the shorter one becomes unity. Then the medium edge will have size q and the larger will have size f.
The u-edges of each layer here become pseudo edges only. In fact, those are the diagonals of the tegum summed faces on the rhombohedral positions.
