| Résumé : | An (n,d)-permutation code of size s is a subset C of Sn with s elements such that the Hamming distance dH between any two distinct elements of C is at least equal to d. In this paper, we give new upper bounds for the maximal size μ(n,d) of an (n,d)-permutation code of degree n with 11 ≤ n ≤ 14. In order to obtain these bounds, we use the structure of association scheme of the permutation group Sn and the irreducible characters of Sn. The upper bounds for μ(n,d) are determined solving an optimization problem with linear inequalities. |
