As abstract polytope dritit is automorph, thereby interchanging the roles of pentagons and pentagrams.
Sadly the above provided acronym is kind of a misnomer, as sidtid allows for several edge facetings using squares, pentagons, and pentagrams only. In fact, not even the mere count of 6 squares and 3 each of pentagons and pentagrams would be unique. Still, it is provided here for historical reasons.
