Space group - Wikipedia
WEBIn mathematics, physics and chemistry, a space group is the symmetry group of a repeating pattern in space, usually in three dimensions. [1] The elements of a space group (its symmetry operations) are the rigid transformations of the pattern that leave it unchanged.
List of space groups - Wikipedia
WEBList of space groups. There are 230 space groups in three dimensions, given by a number index, and a full name in Hermann–Mauguin notation, and a short name (international short symbol). The long names are given with spaces for readability. The groups each have a point group of the unit cell.

WEBApr 23, 2024 · The 230 space groups are unique ways of describing the symmetry of a three-dimensional object. They are mathematical groups that not only describe the point symmetry but also account for full and partial translations in a periodic object in space. The International Tables categorize them by crystal system (rather than by lattice system).
Space group | Symmetry, Point Groups & Crystallography
WEBSpace group, in crystallography, any of the ways in which the orientation of a crystal can be changed without seeming to change the position of its atoms. These changes may involve displacement of the whole structure along a crystallographic axis (translation), as well as the point group operations.

WEBSpace groups identify the possible ways to describe the rotational and translational symmetry of crystalline structures in real space. As we have seen, these aspects of 3-d crystalline symmetry are separately described by 32 crystallographic point groups and 14 Bravais lattices.
