COMMENTS
Conjectures for o.g.f.s for this type of sequences appear in the PhD thesis by Simon Plouffe. See A001552 for the reference. These conjectures are proved in the link given in A196837. - Wolfdieter Lang, Oct 15 2011

FORMULA
a(n) = Sum_{j=1..10} j^n, n >= 0.
E.g.f.: exp(x) + exp(2*x) + exp(3*x) + exp(4*x) + exp(5*x) + exp(6*x) + exp(7*x) + exp(8*x) + exp(9*x) + exp(10*x). - Vladeta Jovovic, May 08 2002
From Wolfdieter Lang, Oct 15 2011: (Start)
O.g.f.: (2 - 11*x) *(5 - 220*x + 4070*x^2 - 41140*x^3 + 247049*x^4 - 896368*x^5 + 1903836*x^6 - 2143152*x^7 + 966240*x^8)/Product_{j=1..10} (1 - j*x).
From the e.g.f. via Laplace transformation. See the proof in a link under A196837.
(End)
a(n) = A001556(n) + A011557(n). - Michel Marcus, Jul 26 2013
