Symbols for space groups

Chapters 4.1 , 4.2 and 4.3 contain extensive explanations and tabulations of the various types of space-group symbols. Chapter 4.3 contains for each crystal system extensive tables of the short, full and extended space-group symbols for various settings and cells. The explanatory text treats, system by system, the `additional symmetry elements' of the space groups. In addition, many examples of those group–subgroup relations are presented which can be read directly from the extended space-group symbols.
