FindClique
FindClique[g] finds a largest clique in the graph g.
FindClique[g,n] finds a clique containing at most n vertices.
FindClique[g,{n}] finds a clique containing exactly n vertices.
FindClique[g,{nmin,nmax}] finds a clique containing between nmin and nmax vertices.
FindClique[g,nspec,s] finds at most s cliques.
FindClique[{g,v},…] finds cliques that include the vertex v only.
FindClique[{v->w,…},…] uses rules v->w to specify the graph g.
