Acronym stotet
Name octagram-tetrahedron duoprism,
octagram duofastegium
Circumradius sqrt[(11-4 sqrt(2))/8] = 0.817247
Face vector 32, 80, 84, 46, 12
Confer
more general:
n,tet-dip  
general polytopal classes:
Wythoffian polytera  

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