La conjecture de Syracuse s’énonce ainsi : quel que soit le nombre que l’on choisisse au départ, on finira par tomber sur 1.
L’énoncé de la conjecturePrenez un nombre entier positif, et appliquez lui le traitement suivant :
s’il est pair, vous le divisez par 2;s’il est impair, vous le multipliez par 3 et vous ajoutez 1.Vous obtenez alors un nouveau nombre, sur lequel vous répétez la procédure. Et ainsi de suite, pour fabriquer une séquence de nombres.Mettons que je parte du nombre 7, voici la séquence que j’obtiens :7,22,11,34,17,52,26,13,40,20,10,5,15,16,8,4,2,1,4,2,1,4,2,1,…
