As abstract polytope gidditdid seems to be isomorphic to sidditdid, saddid, and gaddid, thereby replacing pentagons and decagrams respectively by retrograde pentagrams and decagons, by retrograde pentagons and decagons, by pentagrams and decagrams. But in fact it is only isomorphic to sidditdid. This is because one hasn't only to consider the actual faces, but also the pseudo faces (holes) as well. Saddid and gaddid have square pseudo faces, while sidditdid and gidditdid have hexagonal holes instead.
