If the discrete interval exchange transformation has two intervals\, they are Christoffel words. Therefore\, perfectly clustering words are a natur al generalization of Christoffel words. In this talk\, an induction on dis crete interval exchange transformation with symmetric permutation will be presented. This induction sends a discrete interval exchange transformatio n with symmetric permutation into another one with the same permutation bu t smaller intervals. Moreover\, the induction leads to morphisms\, sending a perfectly clustering word to another perfectly clustering word. Finally \, a new bijection between perfectly clustering words and band bricks over certain gentle algebras will be presented.\nslides\n\nhttps://www.i2m.uni v-amu.fr/wiki/Combinatorics-on-Words-seminar/_media/seminar2023:20230508la pointe.mp4\n\n \;\n\n\n\nThe address of the Zoom meeting is https://zo om.us/j/92245493528 .
