We have a third formulation for the Ramsey number R (4, 3): For a graph G with at least R (4, 3) nodes, either G contains K 4 or G c contains K 3 . Since the relation between complementary graphs is symmetric, R (4, 3) = R (3, 4). A fourth formulation arises in the study of chromatic graphs. A graph is n-colored if its of its edges is uniquely ...
