As abstract polytope sople is isomorphic to sistople, thereby replacing octagons by octagrams, resp. op by stop, resp. sodip by sistodip.

All cubes in here clearly are used as square prisms only. This simply is derived from the individual components, the sodips. But now the square symmetry of the one sodip cancels down the full eightfold one of the other in either of the two orthogonal subspaces. Therefore we get now "lacing cubes" (which are just underneath a single octagon) and to be distinguished "para cubes" (which are parallel to the ops). And thence the lacing squares of the two groups as well are to be distinguished. And therefore the lacing edges of those lacing squares as well have to be distinguished. Thus the octagons would get alternating sides out of the latter ones. And likewise the squares of the ops too will be alternating.
