prime triplet : ウィキペディア英語版 | prime triplet In mathematics, a prime triplet is a set of three prime numbers of the form (''p'', ''p'' + 2, ''p'' + 6) or (''p'', ''p'' + 4, ''p'' + 6).〔Chris Caldwell. (The Prime Glossary: prime triple ) from the Prime Pages. Retrieved on 2010-03-22.〕 With the exceptions of (2, 3, 5) and (3, 5, 7), this is the closest possible grouping of three prime numbers, since one of every three sequential odd numbers is a multiple of three, and hence not prime. ==Examples==
The first prime triplets are (5, 7, 11), (7, 11, 13), (11, 13, 17), (13, 17, 19), (17, 19, 23), (37, 41, 43), (41, 43, 47), (67, 71, 73), (97, 101, 103), (101, 103, 107), (103, 107, 109), (107, 109, 113), (191, 193, 197), (193, 197, 199), (223, 227, 229), (227, 229, 233), (277, 281, 283), (307, 311, 313), (311, 313, 317), (347, 349, 353), (457, 461, 463), (461, 463, 467), (613, 617, 619), (641, 643, 647), (821, 823, 827), (823, 827, 829), (853, 857, 859), (857, 859, 863), (877, 881, 883), (881, 883, 887)
