This definition has been superseded and is retained here only for archival purposes. Use instead '_space_group_symop_id'


   A code identifying each entry in the _symmetry_equiv_pos_as_xyz
   list. It is normally the sequence number of the entry in that
   list, and should be identified with the code 'n' in
   _geom_*_symmetry_ codes of the form 'n_klm'.

   In order for the defaults to work correctly, the identity
   operation should have _space_group_symop_id or
   _symmetry_equiv_pos_site_id set to 1, and
   _space_group_symop_operation_xyz or
   _symmetry_equiv_pos_as_xyz set to x,y,z; 
   i.e. the operation labelled 1 should be the identity
