This resulted in the Pocklington primality test. However, as this test requires a partial factorization of n − 1 the running time was still quite slow in the worst case. The first deterministic primality test significantly faster than the naive methods was the cyclotomy test; its runtime can be proven to be O((log n) ), where n is the number to test for primality and … ultimate ironman thieving

Fermat's little theorem (see also Euler's totient function) states, that for a prime number p and a coprime integer a the following equation holds: a p − 1 ≡ 1 mod p.
