Acronym quititip Name quasitruncated-tesseract prism Circumradius sqrt[11-6 sqrt(2)]/2 = 0.792893 Coordinates ((sqrt(2)-1)/2, (sqrt(2)-1)/2, (sqrt(2)-1)/2, 1/2, 1/2)   & all permutations in all but last coord., all changes of sign

As abstract polytope quititip is isomorphic to tattip, thereby replacing the octagrams by octagons, resp. quith by tic and stop by op, resp. quithip by ticcup and quitit by tat.
