Suppose G is a graph. The chromatic Ramsey number rc(G) of G is the least integer m such that there exists a graph F of chromatic number m for which the following is true: For any 2-colouring of the edges of F there is a monochromatic subgraph isomorphic to G. Let Mn = minfrc(G) : (G) = ng. It was conjectured by S. A. Burr, P.
