1 | {1}
2 | {1, 2}
3 | {1, 2, 3}
4 | {1, 2, 3, 5}
5 | {1, 3, 4, 5, 6}
6 | {1, 3, 4, 5, 6, 7}
7 | {1, 2, 5, 6, 7, 8, 9}
8 | {1, 2, 5, 6, 7, 8, 9, 11}
9 | {1, 2, 5, 6, 7, 8, 9, 11, 13}
10 | {1, 2, 5, 7, 8, 9, 11, 12, 13, 15}
11 | {1, 2, 5, 7, 8, 9, 11, 12, 13, 15, 17}
12 | {1, 2, 5, 7, 8, 9, 11, 12, 13, 15, 17, 19}
13 | {1, 5, 6, 7, 9, 11, 13, 14, 15, 16, 17, 19, 20}
14 | {1, 2, 5, 7, 11, 12, 13, 16, 17, 18, 19, 20, 21, 23}
For n = 4, the set {1,2,3,4} does not have distinct products because 2*2 = 1*4. However, the set {1,2,3,5} does have distinct products because 1*1, 1*2, 1*3, 1*5, 2*2, 2*3, 2*5, 3*3, 3*5, and 5*5 are all distinct.
