_space_group_magn.point_group_number

Definition:

   

     Each of the 122 crystallographic magnetic point groups can be
     associated with exactly one crystallographic non-magnetic space
     group by removing the time-reversal component from each group
     operator.  The identifying number for each such group is taken
     from the "Survey of 3-dimensional magnetic point group types"
     from the "Magnetic Group Tables" of D.B. Litvin.  This number is
     composed of three integers: (1) an integer from 1 to 32 that
     corresponds to the non-magnetic point group; (2) an integer that
     runs sequentially over each of the magnetic point groups
     associated with a given non-magnetic point group; and (3) a
     redundant third integer that runs from 1 to 122.
