Denote by \u03c7n the principal character modulo n. In Section 3 we prove some new congruences for the sums T r,k (n) = n r ] i=1 (\u03c7n(i) i k) (mod n s+1) for s \u2208 {0, 1, 2}, for all divisors r of 24 and for some natural numbers k.We obtain 82 new congruences for T r,k (n), which generalize those obtained in [Ler05], [Leh38] and [Sun08] if n = p is an odd prime. Section 4 is an appendix by the second and third named authors. It contains some new congruences for the sums Ur(n) = n"},"keywords":[["Congruence"],["generalized Bernoulli number"],["special value of L-function"],["ordinary Bernoulli number"],["Bernoulli polyno- mial"],["Euler number"],"2010 Mathematics Subject Classification. primary 11B68; secondary 11R42, 11A07","[MATH] Mathematics [math]"]}
