Using the unit operations that produce arbitrary topological transfo~ations in a 4-connected space-filling structure of trivalent convex polyhedra it is shown that the average number of faces, F, in the individual cells (grain boundaries in isolated grains) cannot be smaller than eight.

Anisotropic polycrystals in which the shear tractions vanish at several locations of the grain boundaries are considered. For three-dimensional polycrystals whose crystals belong to the tetragonal, hexagonal or trigonal class, it is shown that the effective thermal expansion tensor is given in terms
