As abstract polytope affidhi is automorph, thereby interchanging the roles of decagons and decagrams.

This polychoron is fissary. More precisely: vertices coincide by two with simplicial vertex figure each (type A). Alternatively those could be considered identified, then having a compound vertex figure instead (type B).
