LambdaComponents

LambdaComponents[g] gives the lambda components of the graph g.

• LambdaComponents[g, {v1, v2, ...}] gives the lambda components that include at least one of the vertices {v1, v2, ...}.
• LambdaComponents[{v -> w, ...}, ...] uses rules v -> w to specify the graph g.

Examples

LambdaComponents[Graph[{1 -> 2, 2 -> 3, 3 -> 1}]]

LambdaComponents[PetersenGraph[5, 2]]
