Acronym sososaz Name small hepteractihepteractihecatonicosoctaexon Circumradius sqrt[9+2 sqrt(2)]/2 = 1.719624 Coordinates ((1+sqrt(2))/2, 1/2, 1/2, 1/2, 1/2, 1/2, 1/2)   & all permutations, all changes of sign

As abstract polytope sososaz is isomorphic to gososaz, thereby replacing octagons by octagrams, resp. by gocco, resp. steth by gittith, resp. sinnont by ginnont, and soxaxog by goxaxog.
