_space_group_Wyckoff.site_symmetry

Name:
_space_group_Wyckoff.site_symmetry

Definition:

   
     The subgroup of the space group that leaves the point fixed.
     It is isomorphic to a subgroup of the point group of the
     space group. The site-symmetry symbol indicates the symmetry
     in the symmetry direction determined by the Hermann-Mauguin
     symbol of the space group (see International Tables for
     Crystallography Volume A, Section 2.2.12).

     Ref: International Tables for Crystallography (2002). Volume A,
      Space-group symmetry, edited by Th. Hahn, 5th ed.
      Dordrecht: Kluwer Academic Publishers.

Examples:

2.22 position 2b in space group No. 94, P 42 21 2

42.2 position 6b in space group No. 222, P n -3 n

2.. Site symmetry for the Wyckoff position 96f in space group No. 228, F d -3 c. The site-symmetry group is isomorphic to the point group 2 with the twofold axis along one of the {100} directions.
