%N A306230 Lexicographically earliest sequence of distinct positive terms such that for any n > 0, G(n) <> G(a(n)) (where G denotes the Golomb's sequence A001462).
%C A306230 This sequence is a self-inverse permutation of the natural numbers.
%C A306230 For any n > 0, let b(n) = a(n) - n; the sequence b is unbounded.
