L=[2 3 1 4;1 4 2 3;4 1 3 2;3 2 4 1]
Suppose Latin L = (li,j ) has order n. We can get n permutations that represent of each number of L. Let s ∈ n, we define permutation symbol of number s by σs such that σs(i) equal to j for which li,j = s. For example, from L in Example , we get σ1, σ2, σ2, σ4 ∈ S4 as permutation symbol of number 1, 2, 3, 4 in L respectively where σ1 = (1 3 2)(4), σ2 = (1)(2 3 4), σ3 = (1 2 4)(3), σ4 = (1 4 3)(2).
How we find permutation symbol in MATLAB?
Thanks
