{0, 1, 2, ...,k}没有等差对的最大子集

a(1)=1, {0,1},
a(2)=3, {0,1,3},
a(3)=6, {0,1,4,6},
a(4)=11, {0,1,4,9,11},
a(5)=17, {0,1,4,10,12,17},
a(6)=25, {0,1,4,10,18,23,25},
a(7)=34, {0,1,4,9,15,22,32,34},
a(8)=44, {}
a(9)=55, {}
a(10)=72, {}
a(11)=85, {}
a(12)=106, {}

A003022——1, 3, 6, 11, 17, 25, 34, 44, 55, 72, 85, 106, 127, 151, 177, 199, 216, 246, 283, 333, 356, 372, 425, 480, 492, 553, 585——目前为止也就这28项。

求助：这 {} 里的数应该怎么样填？谢谢！！！
