Abstract

Part 8 provides the theoretical background to the data in the tables and diagrams of Volume A. Chapter 8.3 is devoted to special topics on space groups. The reader finds sections on the conventional crystallographic coordinate systems, on crystallographic point orbits and their distribution into Wyckoff positions according to their site symmetries, on sub‐ and supergroups of space groups, on the space‐group generators used in Volume A and on normalizers of space groups.
