The Croft Spiral Sieve, a very efficient multiplicative sieving algorithm derived from the set of all numbers not divisible by 2, 3, & 5, reveals the perfectly symmetrical deterministic process, employing 8 progressively expanding "chord" patterns, whereby the final post-factorization result is all primes >5 up to a given n: www.primesdemystified.com
