Abstract
New lower bounds for seven classical Ramsey numbers are obtained by considering some circulant graphs Gn(Ai)Gn(Ai) with n≥142n≥142 whose orders might be either prime or not. The results areR(3,24)≥143,R(3,25)≥153,R(3,26)≥159,R(3,27)≥167R(3,24)≥143,R(3,25)≥153,R(3,26)≥159,R(3,27)≥167,R(3,28)≥172,R(3,29)≥182,R(3,30)≥187R(3,28)≥172,R(3,29)≥182,R(3,30)≥187.
