Pocklington primality test information


In mathematics, the Pocklington–Lehmer primality test is a primality test devised by Henry Cabourn Pocklington[1] and Derrick Henry Lehmer.[2] The test uses a partial factorization of to prove that an integer is prime.

It produces a primality certificate to be found with less effort than the Lucas primality test, which requires the full factorization of .
