Crystal structure determination of polytypes with diffraction methods can be divided into two steps. The first step is the structure determination of the building unit of the polytypic substance (in most cases layers). The second step is the determination of the stacking sequence of the corresponding building units. The stacking can be ordered as well as disordered. Various methods for solving these problems are described. The aim of this paper is to treate these methods from a uniform point of view.
