ISMAGS.analyze_symmetry

ISMAGS.analyze_symmetry(graph, node_partitions, edge_colors)

Find a minimal set of permutations and corresponding co-sets that describe the symmetry of subgraph.

Returns

set[frozenset]

The found permutations. This is a set of frozenset of pairs of node keys which can be exchanged without changing subgraph.

dict[collections.abc.Hashable, set[collections.abc.Hashable]]

The found co-sets. The co-sets is a dictionary of {node key: set of node keys}. Every key-value pair describes which values can be interchanged without changing nodes less than key.
