Theorem pockthi 12499
Description: Pocklington's theorem, which gives a sufficient criterion for a number  N to be prime. This is the preferred method for verifying large primes, being much more efficient to compute than trial division. This form has been optimized for application to specific large primes; see pockthg 12498 for a more general closed-form version. (Contributed by Mario Carneiro, 2-Mar-2014.)
