Acronym ... Name 2tic (?) Circumradius sqrt[7+4 sqrt(2)]/2 = 1.778824 Vertex figure 2[6/2,8,8] Snub derivation Coordinates ((1+sqrt(2))/2, (1+sqrt(2))/2, 1/2)   & all permutations, all changes of sign General of army tic Colonel of regiment tic Confer non-Grünbaumian master: tic

Looks like a compound of 2 truncated cubes (tic), and indeed vertices, edges, and {8} all coincide by pairs.
