A note about words which coincide except in one position

Combinatorics 2025-10-20 v1

Abstract

In this short note, we show that a result about words which coincide except in one position given as an exercise in Lothaire's Algebraic Combinatorics on Words is false. Moreover, we derive a modified statement which allows us to fix the proof of a theorem which originally used the result of this exercise.
