%F a(n) = A250470(A003961(n)).

%F As a composition of related permutations:

%F a(n) = A266403(A266415(n)).

%F Other identities. For all n >= 0:

%F A000035(a(n)) = A000035(n). [This permutation preserves the parity of n.]

%F A020639(a(n)) = A020639(n). [More generally, it preserves the smallest prime dividing n.]

%F A055396(a(n)) = A055396(n).

%o (Scheme) (define (A266646 n) (A250470 (A003961 n)))

%Y Inverse: A266645.

%Y Cf. A000035, A020639, A055396, A003961, A250470.

%Y Related permutations: A249817, A249818, A266403, A266415.
