   Hermann-Mauguin space-group symbol. Note that the Hermann-Mauguin
   symbol does not necessarily contain complete information
   about the symmetry and the space-group origin. If used, always
   supply the FULL symbol from International Tables for
   Crystallography Vol. A (2002) and indicate the origin and
   the setting if it is not implicit. If there is any doubt
   that the equivalent positions can be uniquely deduced from
   this symbol, specify the _symmetry_equiv_pos_as_xyz
   or *_Hall data items as well. Leave spaces between
   symbols referring to different axes.


'P 1 21/m 1'
'P 2/n 2/n 2/n (origin at -1)'
'R -3 2/m'
