equivalents_info#

System.equivalents_info(
self: System,
key: str,
) → tuple[list[Cluster], list[int], list[Annotated[numpy.typing.NDArray[numpy.int64], '[3, 1]']]]#

Get the “equivalents_info” for a local cluster expansion basis set

Parameters:

key (str) – The local basis set name, local cluster expansion name, local multi-cluster expansion name, or event type name.

Returns:

  • phenomenal_clusters (list[Cluster]) – The phenomenal clusters of the local basis sets

  • equivalent_generating_op_indices (list[int]) – Indices of the factor group operations that generate the phenomenal clusters from the prototype.

  • translations (list[np.ndarray]) – The translations, applied after the equivalent generating factor group operations, that result in the equivalent phenomenal clusters.
