Decoded. For every \(k\) with \(3 \le k \le 5\) and every bound \(N\) there exists a \(k\)-\(\bar\omega \)-critical tournament on more than \(N\) vertices: the \(k\)-critical tournaments form an infinite family. (“\(T\) is \(k\)-critical” unfolds per 2.11: \(\bar\omega (T) = k\) and \(\bar\omega (T - v) = k - 1\) for every vertex \(v\).)
