A Lower Bound for R(5,6)

Combinatorics 2023-10-27 v1

Abstract

The known lower bound for the the classical Ramsey number R(5,6)R(5,6) is improved from 5858 to 5959. The method used to construct the graph is a simple variant of computational methods that have been previously used to construct Ramsey graphs. The new method uses the concurrent programming features of the {\em Go} programming language.
