     In this paper we define a permutation code (that is, a bijection between permutations and subexcedant sequences) and show the more general result that two ${\displaystyle 5}$-tuples of set-valued statistics on the set of permutations and on the set of subexcedant sequences, respectively, are equidistributed.
