Abstract: Consider a finite nonnull graph G with no loops or multiple edges and no isolated points. Its Ramsey number $ r(G)$ is defined as the minimum number p such that every 2-coloring of the lines of the complete graph $ {K_p}$ must contain a monochromatic G. This generalizes the classical diagonal Ramsey numbers $ r(n,n) = r({K_n})$ . We obtain the exact value of the Ramsey number of every such graph with at most four points.
