The application of the theory of superspace groups to the incommensurate composite crystal is reviewed. An introduction is given of the methods for assignment of the diffraction pattern, description of the symmetry, and determination and description of the crystal structure especially for a composite crystal with a four-dimensional symmetry. Some discussions are given about interatomic distances and the relation between the three-dimensional and four-dimensional lattices.
