The International Tables for Crystallography is an eight-book series that outlines the standard notations for formatting, describing and testing crystals. The series contains books that covers analysis methods and the mathematical procedures for determining organic structure through x-ray crystallography, electron diffraction, and neutron diffraction.

WebDefinition. From any point of the three-dimensional Euclidean space the symmetry operations of a given space group G generate an infinite set of points, called a crystallographic orbit.The space group G is called the generating space group of the orbit. Two crystallographic orbits are said to be configuration-equivalent if and only if their … WebJun 14, 2024 · Definition. A crystallographic group or space group in dimension n n is a subgroup of the corresponding Euclidean group, hence of the isometry group of Euclidean space ℝ n \mathbb{R}^n, that contains a (maximal) lattice in ℝ n \mathbb{R}^n as a subgroup, and is contained within the automorphism group of that lattice.
