Acronym tuquith
Name blend of 2 quasitruncated cubes
 
Circumradius sqrt[7-4 sqrt(2)]/2 = 0.579471
Vertex figure [3,(8/3)2], [3,8/3,3/2,8/5]
Coordinates
  • ((sqrt(2)-1)/2, (sqrt(2)-1)/2, 1/2)   & all permutations, all changes of sign
  • ((sqrt(2)-1)/sqrt(2), 0, 1/2)            & permutations in all but last coordinate, all changes of sign
Dihedral angles
  • between {8/3} and {8/3}:   90°
  • between {3} and {8/3} (at quith edges):   arccos(1/sqrt(3)) = 54.735610°
  • between {3} and {8/3} (at pseudo {8/3}):   arccos(sqrt(2/3)) = 35.264390°

blend-component:
quith  

This blend is obtained from 2 mutually gyrated quiths.

As abstract polytope tuquith is isomorphic to tutic, thereby replacing octagrams by octagons.
