Name pinnip+5 2thah (?)
Circumradius sqrt(3/5) = 0.774597
General of army rap
Colonel of regiment rap
Confer pinnip  

Vertices, edges and some triangles coincide by 3, the squares coincide by pairs, in fact this polychoron contains the Grünbaumian double cover 2thah as one type of cells. When omitting these (and reconnecting the still incident elements) one ends with pinnip.
