%N Numerators of sum_{k=1..n} 1/k^10 =: Zeta(10,n).

%C a(n) gives the partial sums, Zeta(10,n), of Euler's Zeta(10). Zeta(k,n) is also called H(k,n) because for k=1 these are the harmonic numbers H(n) = A001008/A002805.

%C For the denominators see A103717 and for the rationals Zeta(10,n) see the W. Lang link under A103345.

%F a(n) = numerator(sum_{k=1..n} 1/k^10).

%F G.f. for rationals Zeta(10, n): polylogarithm(10, x)/(1-x).
