As abstract polytope scufgi is isomorphic to scuffi, thereby replacing pentagrams by pentagons.
This polyhedron either can be considered as a faceting of sissid or else could be constructed as a blend from 3 copies of stappy, when taken all coincident with one single triangle, but mutually in rotated fashion.
