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

Index entries for sequences related to sigma(n)

a(n) = A326053(n) - n = (A000203(n) - A008833(n)) - n.

a(n) = A326055(n) - A033879(n).

(PARI)

A008833(n) = (n/core(n));

A326053(n) = (sigma(n)-A008833(n));

A326054(n) = (A326053(n)-n);
