Acronym ... Name 2ex (?) Circumradius (1+sqrt(5))/2 = 1.618034 Inradius sqrt[(9+4 sqrt(5))/8] = 1.497676 General of army ex Colonel of regiment ex Confer non-Grünbaumian master: ex   Grünbaumian relatives: ex+fix   2ex+fix   3ex+fix   3ex+2fix+gaghi

Looks like a compound of 2 ex with vertices and edges identified, while faces and cells coincide by pairs.

As abstract polytope 2ex is isomorphic to 2gax, thereby replacing {10/2} edge figures by {10/4} ones resp. replacing 2ike vertex figures by 2gike ones.
