Acronym ... Name 2ridditdy (?) Circumradius sqrt(3) = 1.732051 General of army rahi Colonel of regiment rissidtixhi Confer non-Grünbaumian master: ridditdy

Looks like a completely coincident compound of 2 copies of ridditdy, in fact all elements coincide by 2.

As abstract polytope 2ridditdy is automorphic, thereby replacing pentagons by pentagrams while ditdid and raded are automorphic too.
