k_clique_communities(G, k, cliques=None)[source]

Find k-clique communities in graph using the percolation method.

A k-clique community is the union of all cliques of size k that can be reached through adjacent (sharing k-1 nodes) k-cliques.

Parameters :

G : NetworkX graph

k : int

Size of smallest clique

cliques: list or generator

Precomputed cliques (use networkx.find_cliques(G))

Returns :

Yields sets of nodes, one for each k-clique community.
