As abstract polytope sidditdiddip is isomorphic to gidditdiddip, thereby replacing retrograde pentagrams and decagons respectively by pentagons and decagrams, resp. replacing sidditdid by gidditdid, stip by pip, and dip by stiddip. – It also is isomorphic to saddiddip, thereby replacing retrograde pentagrams by retrograde pentagons, resp. replacing sidditdid by saddid and stip by pip. – Finally it is isomorphic to gaddiddip, thereby replacing retrograde pentagrams and decagons respectively by pentagrams and decagrams, resp. replacing sidditdid by gaddid and dip by stiddip.
