On multiperiodic words

corrigé par Corrigendum: On multiperiodic words

In this note we consider the longest word, which has periods p 1 ,⋯,p n , and does not have the period gcd(p 1 ,⋯,p n ). The length of such a word can be established by a simple algorithm. We give a short and natural way to prove that the algorithm is correct. We also give a new proof that the maximal word is a palindrome.
