In mathematics, the Pocklington–Lehmer primality test is a primality test devised by Henry Cabourn Pocklington and Derrick Henry Lehmer to decide whether a given number is prime. The output of the test is a proof that the number is prime or that primality could not be established. ==Pocklington criterion== The test relies on the Pocklington Theorem (Pocklington criterion) which is formulated as follows: Let be an integer, and suppose there exist numbers ''a'' and ''q'' such that (1) ''q'' is prime, and (2) (3) Then is prime.〔Koblitz, Neal, A Course in Number Theory and Cryptography, 2nd Ed, Springer,1994〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Pocklington primality test」の詳細全文を読む スポンサード リンク
