Acronym tocto Name truncated octeract Circumradius sqrt[(11+7 sqrt(2))/2] = 3.232607 Inradiuswrt. oca (7+4 sqrt(2))/4 = 3.164214 Inradiuswrt. tasa [1+sqrt(2)]/2 = 1.207107 Dihedral angles (at margins) at hop between oca and tasa:   arccos[-1/sqrt(8)] = 110.704811° at tox between tasa and tasa:   90° Confer analogs: truncated hypercube tCn

As abstract polytope tocto is isomorphic to queto, thereby replacing the octagons by octagrams, resp. tic by quith, resp. tat by quitit, resp. tan by quittin, resp. tox by quotox, resp. tasa by quitasa.
