 OFFSET 1,2 COMMENTS Values of k for which A239876(k) / k is an integer. A239876 = partial sums of A229110 where A229110(n) = antisigma(n) mod n = A024816(n) mod n. a(26) > 3*10^11. - Giovanni Resta, Mar 29 2014 LINKS Table of n, a(n) for n=1..25. EXAMPLE a(4) = 14 is in the sequence because A239876(14) / 14 = 70 / 14 = 5 is an integer. PROG (Magma) [n: n in [1..1000] | u eq 0 where u is ((&+[(k*(k+1)div 2 - SumOfDivisors (k)) mod k: k in [1..n]]) mod n)] CROSSREFS Cf. A024816, A229110, A239876.
