Abstract
The Farey sequences can be used [1] to create the Eulers totient function (), by identifying the fractions for number that did not occur in all Farey sequences up to . This function creates, when divided by n-1, what is here called the Primety measure, which is a measure of how close to being a prime number n is. () has maximum for all prime numbers and minimum that decreases non-uniformly with n. Thus is the Primety function, which permits to designate a value of Primety of a number . If , then n is a prime. If <, n is not a prime, and the further is from n, the less n is a prime. () and is generalized to real numbers through the use of real numbered Farey sequences. The corresponding numerical sequences are shown to have interesting mathematical and artistic properties.
