%F a(n) = A250470(A263273(A250469(n))).

%F As a composition of related permutations:

%F a(n) = A266415(A266645(n)) = A266646(A266416(n)).

%F a(n) = A250472(A264996(A250471(n))).

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

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

%o (Scheme) (define (A266403 n) (A250470 (A263273 (A250469 n))))
