摘要🫙：Motivated by group algebra codes, permutation codes are introduced and self-dual permutation codes are studied. Further, a characterization of indecomposable orthogonal decompositions of symmetric semisimple modules and a criterion for the hyperbolic symmetric semisimple modules are obtained, and some applications to the self-dual permutation codes are shown.
