As abstract polytope gefridit xethi is isomorphic to gefirdit xethi, thereby interchanging the roles of pentagrams and pentagons, resp. replacing doe by gissid and sidtid by gidtid.

Looks like the compound of gridtathi and teppix. Indeed, vertices coincide by 4, edges by 3, and triangles and hexagons each coincide by pairs.
