Index entries for sequences that are permutations of the natural numbers

Formula

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

As a composition of related permutations:

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

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

Other identities. For all n >= 0:

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