Acronym ohix
Name octagon - hexateron duoprism
Circumradius sqrt[(17+6 sqrt(2))/12] = 1.457317
Confer
more general:
n,hix-dip  
general polytopal classes:
segmentoexa  

As abstract polytope ohix is isomorphic to stohix, thereby replacing octagons by octagrams, resp. op by stop, resp. otet by stotet, resp. open by stopen.
