class chemcoord.PointGroupOperations(sch_symbol, operations, tolerance=0.1)[source]

Defines a point group as sequence of symmetry operations.

  • sch_symbol (str) – Schoenflies symbol of the point group.
  • operations (numpy.ndarray) – Initial set of symmetry operations. It is sufficient to provide only just enough operations to generate the full set of symmetries.
  • tolerance (float) – Tolerance to generate the full set of symmetry operations.
