_space_group_name_Hall

Definition:

   Space-group symbol defined by Hall.

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

   _space_group_name_Hall uniquely defines the space group and
   its reference to a particular coordinate system.
