Collection: Permutations

-----------------------------------------------------------------------------
Description: The minimal number of transpositions needed to sort a permutation in either direction.

For a permutation $\sigma$, this is $\min\{ \operatorname{inv}(\sigma),\operatorname{inv}(\tau)\}$ where $\tau$ is the reverse permutation sending $i$ to $\sigma(n+1-i)$.

    n = len(pi)
    l1 = len(pi.inversions())
    l2 = binomial(n,2)-l1
    return min(l1,l2)
