muEC::SG::Perm2Length – calculates the length of a permutation
The muEC::SG::Perm2Length function calculates the length of the permutation perm, that is its number of inversions. This is also the minimal length of an expression of the permutation as a product of simple transpositions, as well as the sum of the components of its code.
Call:
muEC::SG::Perm2Length(perm)
Parameters:
