As abstract polytope sirsashi is isomorphic to sirgaghi, thereby interchanging pentagrams and pentagons, resp. replacing id by gid.

If considered with according densities, then quipdohi can be thought of as the external blend of 1 rofix + 120 sissidaradeds + 1200 triddips + 120 iddips. This decomposition is described as the degenerate segmentoteron ox5/2oo5xx3oo&#x.
