Antti Karttunen, Table of n, a(n) for n = 1..10000 (based on Hans Havermann's factorization of A156552)

Index entries for sequences related to binary expansion of n

Index entries for sequences computed from indices in prime factorization

Index entries for sequences related to sigma(n)

a(n) = A000120(A323243(n)).

a(A000040(n)) = n.

(PARI) A324729(n) = hammingweight(A323243(n)); \\ Needs also code from A323243.

Cf. A000120, A323243, A324730.

Sequence in context: A323355 A108230 A334202 * A253558 A061395 A290103

Adjacent sequences: A324726 A324727 A324728 * A324730 A324731 A324732
