Antti Karttunen, Table of n, a(n) for n = 0..16383

Index entries for sequences that are permutations of the natural numbers

a(n) = A264965(2*n) / 2.

As a composition of related permutations:

a(n) = A263272(A057889(n)).

(Scheme, two alternative definitions)

(define (A266641 n) (/ (A264965 (* 2 n)) 2))

(define (A266641 n) (A263272 (A057889 n)))

Inverse: A266642.
