Let $\rho=(1,\dots,n)$ and $\sigma=(1,2)$. Then, for a permutation $\pi\in\mathfrak S_n$, this statistic is $$\min\{k\mid \pi=\rho^{i_0}\sigma\rho^{i_1}\sigma\dots\rho^{i_{k-1}}\sigma\rho^{i_k}, 0\leq i_0,\dots,i_k < n\}.$$ Put differently, it is the minimal length of a factorization into cyclic shifts of the transposition $(1,2)$ (see [[St001076]]) of any of the permutations $\rho^k\pi$ for $0\leq k < n$. ----------------------------------------------------------------------------- References: [1] Ryazanov, A.
