%N Smallest positive number divisible by n which is not of the form a(i), a(i)+a(j), or |a(i)-a(j)| for i and j <= n-1.

%C Same as A122544, except that both sums and absolute differences of previous terms are disqualified.

%e a(3) cannot be 3 because 3 = 4-1 and 1 and 4 are both previous terms.

%Y Cf. A122537, A122544.

%K nonn

%O 1,2
