为什么外国的素数网站上 16生素数： k=16 s=60 B={0 4 6 10 16 18 24 28 30 34 40 46 48 54 58 60} 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 而不是 k=16 s=60 B={0 2 6 8 12 18 20 26 30 32 36 42 48 50 56 60} 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71

与K-生素数的定义有关，见 http://mathworld.wolfram.com/PrimeConstellation.html k consecutive numbers such that the difference between the first and last is, in some sense, the least possible. More precisely, a prime -tuplet is a sequence of consecutive primes (p1,p2,p3...pk ) with pk-p1=s(k), where s(k) is the smallest number for which there exist k integers b1

所以，当 k=16 s=60 B={0 2 6 12 14 20 26 30 32 36 42 44 50 54 56 60} 首素数最小的序列如下（http://anthony.d.forbes.googlepages.com/ktmin.txt）： 47710850533373130107 + 0, 2, 6, 12, 14, 20, 26, 30, 32, 36, 42, 44, 50, 54, 56, 60 (1997, TF and Joerg Waldvogel)
