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 .
