%N Additive bases: a(n) is the least integer such that there is an n-element set of nonnegative integers, the sums of pairs of which are distinct and at most a(n).
%C By definition, these terms are twice the terms of A003022, see comment there. - _Bernd Mulansky_, Jun 25 2021
%C Lexicographically first basis that yields a(16) = 354 is {0,1,4,11,26,32,56,68,76,115,117,134,150,163,168,177}. - _Fausto A. C. Cariboni_, Nov 01 2017
