Magnetic group maximal subgroups of index < or =4.
The one-, two- and three-dimensional magnetic space groups and the two- and three-dimensional magnetic subperiodic groups are considered. The maximal subgroups of index < or =4 of a representative group of each type in the reduced superfamilies of these magnetic groups are tabulated.
