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

Formula

a(1) = 0; and for n > 1, a(n) = A333793(n) - A333793(n-1).

a(p) = 0 for all primes p. (May obtain zero values also on some nonprimes).

Prog

(PARI) A333792(n) = if(1==n, 0, A333793(n)-A333793(n-1)); \\ Other code as in A333793.
