Acronym otet
Name octagon-tetrahedron duoprism,
octagon duofastegium
Circumradius sqrt[(11+4 sqrt(2))/8] = 1.442951
Confer
more general:
n,tet-dip  
general polytopal classes:
segmentotera  

As abstract polytope otet is isomorphic to stotet, thereby replacing octagons by octagrams, resp. op by stop, resp. todip by tistodip.
