As abstract polytope 2sadtifady is isomorphic to 2gadtifady, thereby replacing pentagons by pentagrams and decagons by decagrams, resp. saddid by gaddid and id by gid.
Looks like a coincidic compound of 2 sadtifady copies. In fact, vertices coincide by 6, edges by 4, and all other elements by pairs.
