 OFFSET 1,2 COMMENTS Observe that a value k can appear in A268755 only after 0,1,...,k-1 have already appeared. This means that this sequence is strictly increasing. Conjectured to be infinite (this is equivalent to the conjecture that every positive integer eventually appears in A268755). (Proof given in comments of A268755). How fast does it grow? Experimentally, it seems like a(n) ~ n^t, with 1 < t <= 2. LINKS László Kozma, Table of n, a(n) for n = 1..1001 EXAMPLE For n = 4, a(4) = 10, since the value 3 first appears in A268755 at position 10. CROSSREFS Cf. A268755, A181391.
