_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 2.1.3.12).

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. |
