As abstract polytope doaid is isomorphic to gissidagid, thereby replacing pentagons by pentagrams resp. replacing does by gissids, paps by staps, and ids by gids.
This monostratic polychoron could be obtained as a bistratic tropical section of ex, when all medial vertices would be diminished in addition (there chopping off a pappy each).
