The clique number is the maximum number of vertices comprising a clique in G. A clique in a graph G is a set of vertices such that all the the vertices are mutually adjacent (they are all connected to each other).
i1 : G = graph({{1, 2}, {1, 3}, {2, 3}, {3, 4}},EntryMode=>"edges"); |
i2 : cliqueNumber G o2 = 3 |
The object cliqueNumber is a method function.
