_space_group.name_H-M_full

Definition:

   
     The full international Hermann-Mauguin space-group symbol as
     defined in Section 2.2.3 and given as the second item of the
     second line of each of the space-group tables of Part 7 of
     International Tables for Crystallography Volume A (2002).

     Each component of the space-group name is separated by a
     space or an underscore character. The use of a space is
     strongly recommended.  The underscore is only retained
     because it was used in old CIFs. It should not be used in
     new CIFs.

     Subscripts should appear without special symbols. Bars should
     be given as negative signs before the numbers to which they
     apply. The commonly used Hermann-Mauguin symbol determines the
     space-group type uniquely but a given space-group type may
     be described by more than one Hermann-Mauguin symbol. The
     space-group type is best described using
     _space_group.IT_number or _space_group.name_Schoenflies. The
     full international Hermann-Mauguin symbol contains information
     about the choice of basis for monoclinic and orthorhombic
     space groups but does not give information about the choice
     of origin. To define the setting uniquely use
     _space_group.name_Hall, or list the symmetry operations
     or generators.
