"Web2. A Lower Bound on the two-color Ramsey Numbers We give an exponential lower bound on the Ramsey numbers using the prob-abilistic method, from [2]. The basic idea is that if nis too small, then graphs without proper monochromatic subgraphs can be chosen with nonzero probability. Theorem 2.1. 2k 2 R(k;k) Proof. " - Small ramsey numbers
