Acronym ... Name 2sprapivady (?) Circumradius sqrt[5+2 sqrt(5)] = 3.077684 General of army rox Colonel of regiment rox Confer non-Grünbaumian master: sprapivady

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

As abstract polytope 2sprapivady is isomorphic to 2gippapivady, thereby replacing decagons by decagrams, resp. by replacing ike by gike and tid by quit gissid.
