%N a(n) = smallest k not already in the sequence such that OEIS entry Ak contains n.
%H <a href="/index/Se#selfies">Index entries for sequences whose definition involves A_n (or An)</a>.
%e A000001 contains 0, so a(0) = 1.
%e A000002 contains 1, so a(1) = 2.
%e k = 10 is the smallest k not yet in the sequence such that Ak = A000010 contains 8, so a(8) = 10.
%Y Cf. A051070, A053169, A053873.
