Computer-Assisted Results for \(n\)-Sided Non-Transitive Dice Taking Face Values in \([n]\)

We consider non-transitivity among dice with \(n\) sides restricted to taking face values in the set \(\{1,…,n\}\). We give a computer-assisted proof that \(n=6\) is the smallest \(n≥3\) which admits a non-transitive cycle of maximum length \(n\) with uniform and minimal winning advantage. For \(n=6\), we identify the two unique non-transitive cycles of length \(6\). We present computational evidence supporting a conjecture that \(n=6\) is the largest \(n≥3\) which admits a non-transitive cycle of maximum length \(n\) with uniform and minimal winning advantage.
