In the Hill cipher, elements of matrices are in the ring of integers modulo the number of characters in the alphabet used, usually n = 26. Therefore, as long as the denominator of a fraction is coprime with n (that is, for n = 26, if the denominator is divisible neither by 2 not by 13 ), that fraction reduces to an integer modulo n. optogenetics annual review
