The main page of the International Tables Symmetry Database (https://symmdb.iucr.org/) is arranged in three parts. The first part (the left-hand column) provides access to the programs and visualizer associated with space-group symmetry: Generators (see Section 2.1), General position (see Section 2.1), Wyckoff positions (see Section 2.2), Normalizers (see Section 2.3) and Interactive 3D visualization (see Section 2.4). The second part (the middle column) provides access to databases, programs and a visualizer related to symmetry relations between space groups: Maximal subgroups (see Section 3.1), Series of isomorphic subgroups (see Section 3.2), Minimal supergroups (see Section 3.3), Group–subgroup relations (see Section 3.4), Graph of maximal subgroups (see Section 3.5) and Supergroups (see Section 3.6). The third part (the right-hand column) provides access to programs and a visualizer related to the database of three-dimensional crystallographic point groups: Generators, General position and Wyckoff positions (see Section 4.1), and Interactive 3D visualization (see Section 4.2). |
