A conjecture of Fraenkel and Simpson states that the number of distinct squares in a finite word is bounded by its length. In this talk, we will review this conjecture from the perspective of the topological proprieties of the Rauzy graphs of . We prove this conjecture by giving a stronger statement: the number of distinct squares in a finite word is bounded by the length of minus the number of distinct letters in .
