COMMENTS
| A005282 is the sequence of smallest numbers such that the pairwise sums of not necessarily distinct elements are all distinct.
Conjecture: 2, 4 and 8 are the only terms n such that n = 2*A005282(k) for some k.

EXAMPLE
| A005282(3) = 4 + 4 = 8 = A005282(4), hence 8 is in the sequence.
A005282(10) = 81, A005282(12) = 123. 81 + 123 = 204 = A005282(15), hence 204 is in the sequence.
