Crystallographic group
From Wikipedia, the free encyclopedia
A crystallographic group is a topologically discrete subgroup of the group of isometries of some geometric space (typically, not necessarily a Euclidean space) with a compact fundamental domain.
For a plane, see wallpaper group.
For 3D Euclidean space, see space group and crystallographic point group.
See also crystallography.
