Webnumber R(k) is the minimum number of vertices a tournament must have to be guaranteedto contain a transitive subtournament of size k, which we denote by TT k. We include a computer-assisted proof of a conjecture by Sanchez-Flores [9] that all TT6-free tournaments on 24 and 25 vertices are subtournaments of ST27, the unique largest … Webevery vertex v2V(T) are both transitive. Alternatively a locally transitive tournament is a tournament that has no occurrences of W 4 nor of L 4, where W 4 and L 4 are the tour-naments of size 4 with outdegree sequences (1;1;1;3) and (0;2;2;2) respectively. On the other hand, a balanced tournament is a tournament with an odd number of vertices 2n+1
