It may, for example, be used to give one of the extended Hermann–Mauguin symbols given in Table 4.3.2.1 of International Tables for Crystallography Vol. A (2002) or a Hermann–Mauguin symbol for a conventional or unconventional setting. Each component of the space-group name is separated by...
The 32 point groups are the symmetry groups of many molecules and of all crystals, so long as only the morphology is considered. Space groups give the symmetry not only of crystal lattices, but also of crystal structures. The space-group symbols for the 14 Bravais lattices are listed in Tab...

Volume A of International Tables for Crystallography is the reference for space-group information. However, the content is not exhaustive because for many space groups a variety of settings may be chosen but not all of them are described in detail or even fully listed. The use of alternative ...
