Notes:
A phase transition between the diamond (Fd\bar3m) and the lonsdaleite types (P63/mmc) may be described as a deformation of a homogeneous sphere packing with three contacts per sphere (type 3/10/o1) in the common subgroup Pnna of Fd\bar3m and P63/mmc. The frequently observed transition between the zinc-blende (F\bar43m) and the wurtzite types (P63mc) may be described in an analogous way as a deformation of a heterogeneous sphere packing in the subgroup Pna21. The proposed model guarantees the three-dimensional connection during the whole transformation process. By this property it is distinguished from other models.
