Site symmetry of the Double Space Groups

Site Symmetry Method
This program implements the so-called site-symmetry approach for double space groups. The method establishes symmetry relations between the localized states (local atomic displacements) and crystal extended states (phonons, electrons, etc.) over the entire Brillouin zone.
Input data:
1. Space group number.
2. k-vector.
3. Wyckoff position.
