WebThe first deterministic primality test significantly faster than the naive methods was the cyclotomy test; its runtime can be proven to be O((log n) c log log log n), where n is the number to test for primality and c is a constant independent of n. Many further improvements were made, but none could be proven to have polynomial running time. http://aashtoresource.org/university/newsletters/newsletters/2016/08/04/behind-the-screens-determining-the-sufficiency-of-mechanical-sieving-devices
