{0, 1, 2, 3, ..., a(n)}没有等和对的最大子集——目前人类只计算到第17项——第16项还是个错家伙!——谢谢mathe!

a(1)=0,  {0},
a(2)=1,  {0, 1},
a(3)=2,  {0, 1, 2},
a(4)=4,  {0, 2, 3, 4},
a(5)=7,  {0, 3, 5, 6, 7},
a(6)=12,  {0, 1, 2, 6, 9, 12},
a(7)=18,  {0, 1, 2, 4, 8, 13, 18},
a(8)=24,  {0, 1, 2, 4, 8, 14, 19, 24},
a(9)=34,  {0, 1, 2, 4, 8, 15, 24, 29, 34},
a(10)=45,  {0, 1, 7, 10, 13, 21, 26, 41, 43, 45},
a(11)=57,  {0, 1, 5, 9, 17, 31, 33, 44, 51, 54, 57},
a(12)=71,  {0, 1, 2,  7, 12 22, 37, 40, 54, 63, 67, 71},
a(13)=86,  {0, 1, 11, 17, 21, 34, 42, 57, 60, 72, 79, 84, 86},
a(14)=105,  {0, 1, 6, 14, 27, 44 54 66, 69, 85, 94, 101, 103, 105},
a(15)=126,  {0, 8, 13, 16, 19, 31, 46, 76, 83, 90, 100, 104, 124, 125, 126},
a(16)=148,  {0, 3, 5, 6, 32, 49, 59, 68, 93, 106, 118, 126, 130, 134, 141, 148},
a(17)=171,——哪位好心网友补充一下?——谢谢!!!

A345731——1, 2, 4, 7, 12, 18, 24, 34, 45, 57, 71, 86, 105, 126, 150, 171,——Table of n, a(n) for n=2 ......17.
A345731——Additive bases: a(n) is the least integer such that there is an n-element set of integers between 0 and a(n), the sums of pairs (of distinct elements) of which are distinct.
