%N A025582 A B_2 sequence: a(n) = least value such that sequence increases and pairwise 
               sums of elements are all distinct.
%H A025582 <a href="Sindx_Br.html#B_2">Index entries for B_2 sequences.</a>
%e A025582 After 0, 1, a(3) cannot be 2 because 2+0 = 1+1, so a(3) = 3.
%Y A025582 See A011185 for more information.
%Y A025582 A010672 is a similar sequence, but there the pairwise sums of distinct
