Item _symmetry.space_group_name_H-M

Description

              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.
