Acronym tetsteth
Name (tet,steth)-duoprism
Circumradius sqrt[(15+4 sqrt(2))/8] = 1.606894

As abstract polytope tetsteth is isomorphic to tetgittith, thereby replacing octagons by octagrams, resp. op by stop and socco by gocco, resp. todip by tistodip, soccope by goccope and steth by gittith, resp. otet by stotet, trasocco by tragocco and stethip by gittithip, resp. tetsocco by tetgocco and trasteth by tragittith.
