From the various dodecahedrons may be derived seven triskaidecahedrons, and from these in turn may be derived seven tetrakaidecahedrons.

These demonstrations (Figures 6, 7, 8, and 9) are operations available to the trigonal, tetragonal tetrakaidecahedra, and triskaidecahedron (Figures 10, 11 and 12).

Beyond 13% of strain, where the SB is already formed, the predominant class is the 13-face polyhedra, in particular the triskaidecahedra characterized by Voronoi index 〈0, 3, 6, 4〉.
