The Stasinski-Voll length of a signed permutation $\sigma$ is $$ L(\sigma) = \frac{1}{2} \#\{(i,j) ~\mid -n \leq i < j \leq n,~ i \not\equiv j \operatorname{mod} 2,~ \sigma(i) > \sigma(j)\}, $$ where $n$ is the size of $\sigma$. ----------------------------------------------------------------------------- References: [1] Stasinski, A., Voll, C.
