contracted_edge(G, edge[, self_loops])

Returns the graph that results from contracting the specified edge.

contracted_nodes(G, u, v[, self_loops])

Returns the graph that results from contracting u and v.

identified_nodes(G, u, v[, self_loops])

Returns the graph that results from contracting u and v.

quotient_graph(G, partition[, …])
