We show that an infinite word s satisfies s = uoutu2 . . . with all ui being different nonempty words and their set being a biprefix code if and only if s is not ultimately periodic. We give also related results, considering in particular arbitrary codes, infix codes and the case of two-sided infini

This paper is concerned with finiteness conditions for finitely generated semigroups. First, we present a combinatorial result on infinite sequences from which an alternative proof of a theorem of Restivo and Reutenauer follows: a finitely generated semigroup is finite if and only if it is periodic
