Abstract
Two aspects of phase transitions in the solid state are discussed, namely the structure of the symmetry group of a plastic crystal and the prediction of plausible pathways for first-order phase transitions. It is explained how group extension theory may be used for the former and how space group representation theory is an essential adjunct of crystallographic considerations in the latter.Keywords
