_symmetry.space_group_name_H-M

Name:
'_symmetry.space_group_name_H-M'

Definition:

   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
   _symmetry.space_group_name_Hall  data items as well. Leave
   spaces between symbols referring to
   different axes.

Examples:

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