We deene a new class of sequences, sequences with grouped factors, in which all factors of a given length occur consecutively at some position. This class contains periodic sequences, Sturmian sequences, but also sequences with maximal complexity. As a particular case, we obtain a new characteristic property of Sturmian words.
