Item 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.
