FORMULA

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

As a composition of related permutations:

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

Other identities. For all n >= 0:

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

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

A055396(a(n)) = A055396(n).

PROG

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