This database is a unique resource that provides more extensive symmetry information than can be found in International Tables for Crystallography Volumes A and A1. This additional symmetry information can either be retrieved directly from the database or simple calculations can be carried out using the database to generate specific data ‘on the fly’. Use of the symmetry database thus facilitates the in-depth study of group-subgroup relations, domain structures and twinning, families of related crystal structures and phase transitions, and the prediction of new crystal structures.
