ABSTRACT
Based on Zanzotto (1996b),1 in this chapter we make explicit the local structure of the wt-nbhds and of the variant structures in them, and we give all the (small) symmetry-breaking stretches that are possible in the configuration space B. To do so, we follow the procedure outlined in §4.4. We give all the information in the case of wt-nbhds of bases ea of maximal symmetry, that is, whose holohedry P (ea) is in the cubic or in the hexagonal system and, as anticipated, we proceed by progressively breaking the symmetry of the center. This information can be used also to cover the cases in which the symmetry of ea is nonmaximal, although the matter is not completely trivial (see Zanzotto (1996b) for some details).
