Looks like a compound of a sishi with idhi. Its vertex figure is a variation of 2ike+gad, in fact f3/2v5o, which in turn looks to the exterior like a doe. Edges coincide by 3 and pentagrams come in coincident pairs.

As abstract polytope sishi+idhi is isomorphic to gaghi+idhi, thereby interchanging pentagrams and pentagons resp. replacing sissid by gad.
