Comments

More than the usual number of terms are displayed, in order to show the difference between this and some closely related sequences. - N. J. A. Sloane, Mar 13 2014

A010879(a(n)) <> A000030(a(n+1));

A130572 is the inverse permutation; A130573(n) = a(a(n));

a(A130575(n)) = A130575(n);

see A130576 and A130577 for record values and where they occur.
