…Furthermore, E. Lucas found that p ≡1 (mod 2 n +2 ) for the prime factor p of F n when n ≧2, and used this to discover the prime factor 7×2 14 +1 of F 12. It is also known that the necessary and sufficient condition for F n to be prime is (mod F n ) (PT Pepin's criterion). There are no known examples of F n being prime when n ≧5. … *Some of the terminology explanations that mention "Pepin, PT" are listed below.

…さらにルカスE.Lucasはn≧2のとき,Fnの素因数pに対してp≡1 (mod 2n+2)であることを見いだし,これを使ってF12の素因数7×214+1を発見した。またFnが素数であるための必要十分条件は (mod Fn)であることも知られている(プパンP.T.Pepinの判定法)。n≧5のときFnが素数である例は知られていない。… ※「Pepin,P.T.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
