Antti Karttunen, Data supplement: n, a(n) computed for n = 1..65537

Index entries for sequences related to binary expansion of n

Index entries for sequences related to sigma(n)

a(n) = n - A324659(n) = n - A318468(n)/2 = n - ((2*n AND sigma(n))/2).

(PARI) A324658(n) = (n-(bitand(2*n, sigma(n))/2));

Cf. A000203, A004198, A318468, A324648, A324659.

Cf. A324652 (positions of zeros).
