Ramsey number r 3 3 3

WebbThe only known exact value for a multi-colored Ramsey number is r ( 3, 3, 3) = 17 (see [ 4 ]). For r ( 3, 3, 3, 3), the upper bound of 64 was established by Sanchez-Flores [ 7] in 1995 while the lower bound of 51 dates back to the 1970s [ 1 ]. Concerning r ( 3, 3, 4), Piwakowski and Radziszowski [ 6] recently proved an upper bound of 29 while ...

If we wanted to brute force check to see that it is not 43, then we would want to check all graphs with 43 vertices. While 43 does not seem like a big number, there are roughly 2 43*42/2 many such graphs (which is roughly 10 271). That is way too big to check by brute force. paige jeans new yorkWebbThus, say, R(3) stands for R(3, 3, 3) which in turn is the same as R(3, 3, 3; 3).
