Maximal Subgroups of Magnetic Space Groups and Subperiodic Groups
Daniel B. Litvin · Acta Crystallographica Section A Foundations of Crystallography · 1996
An algorithmic procedure is presented to determine the maximal subgroups of magnetic space groups and subperiodic groups from the maximal subgroups of non-magnetic space groups and subperiodic groups. As an example of the application of this procedure, the maximal subgroups of the magnetic frieze groups are derived and tabulated.
