Acronym gisdiddip Name great-snub-dodekicosidodecahedron prism Colonel of regiment (is itself not locally convex, but no other uniform polyhedral members) Externallinks

As abstract polytope gisdiddip is isomorphic to sididdip, thereby replacing the prograde pentagrams by (prograde) pentagons, while retrrograde pentagrams keep unchanged, resp. replacing some stip by pip and gisdid by sided.
