摘要：

It is possible to understand, or at least rationalize, the occurrence of pseusosymmetry elements in some crystals as a consequence of a higher symmetry in a two-dimensional layer being obscured by the three-dimensional packing of the layers. Six examples, including both simple compounds and cocrystals and involving six different symmetries, are described.
