First, we prove that if the language Sym = {w wR/w ε {a,b}*} belongs to Fσ(L), the smallest substitution closed full AFL generated by the family L, then there exists a language L ε L such that Sym ε C(L). We prove that this property does not hold for C1={anbn/n ≥0 }, by characterizing the languages \(L \subseteq C_1 \) such that C1 ε C(L).
