_space_group.name_Hall

Definition:

   Space-group symbol defined by Hall.

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

   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.
