The ratio between the numbers of the step sizes (associated with the direction of the billiard ball) may be rational (resulting in a periodic scale) or irrational (resulting in an aperiodic scale). | '''Hypercubic billiard words''', '''cutting sequences''', or '''cutting words'''<ref name="vuillon">Vuillon, L.

Regarded as scales, they are called '''billiard scales''', which are one possible generalization of [[MOS]] scales to [[arity|larger alphabets]]. | Regarded as scales, they are called '''billiard scales''', which are one possible generalization of [[MOS]] scales to [[arity|larger alphabets]]. | ||
