The frequencies

The bar graph of Figure 7 shows the frequency with which each dice appears in different non-transitive cycles. A finer analysis of the graph shows that bars with the same height appear in pairs. If \(n_{1}\leq n_{2}\leq...\leq n_{5}\leq n_{6}\) and \(m_{1}\leq m_{2}\leq...\leq m_{5}\leq m_{6}\) are the number of spots in each dice of such a pair, they are related by the formula \(n_{i}+m_{i}=7\) for all \(i=1,...,6.\)
