Vidéo d’explication

J’ai également fait une version visuelle dans le cas du cube 2x2x2

Le programme calcule l’ordre d’un mouvement, c’est-à-dire combien de fois il faut le répéter pour revenir au point de départ. Il est suffisamment général pour pouvoir s’appliquer au Rubik’s cube classique, au pocket ou à d’autres jeux comme les anneaux Hongrois.

>> ordre("FR") donnera 15 (Le mouvement est face avant + droite)
Utilisez des minuscules pour tourner une face en sens inverse.

Pour passer d’un objet à un autre, faire un copier-coller des constantes ci-dessous.
