R0043-22136 · q-20261014-advance-20261110-r06-mobius-inversion-finite-divisors-0086 ## Original question and givens Use positive integer n=156, exact integer arithmetic function f(k)=a*k+b with a=11, b=1. F(m) sums f(d) over every positive divisor d of m. Inversion uses mu(d)*F(m/d); complete prime multiplicities determine mu, with mu(1)=1. Do not replace d|m by d≤m or use only prime/proper divisors. Omit divisor=1. Give (n, all_divisors, omitted_divisor, partial_divisors, complete_value, partial_value, f_n, incomplete_certificate, boundary). - G001 — Use positive integer n=156, exact integer arithmetic function f(k)=a*k+b with a=11, b=1.
