Abstract:Let Ln be the finite language of all n! strings that are permutations of n different symbols (n ¿ 1). We consider contextfree grammars Gn in Chomsky normal form that generate Ln. In particular we study a few families {Gn}n¿1, satisfying L(Gn) = Ln for n ¿ 1, with respect to their descriptional complexity, i.e. we determine the number of nonterminal symbols and the number of production rules of Gn as functions of n.
