Harry J. Smith, Table of n, a(n) for n = 0..500
Index entries for linear recurrences with constant coefficients, signature (11,-55,165,-330,462,-462,330,-165,55,-11,1).
FORMULA
a(n) = (n^10 + 5*n^6 + 6*n^5 + 4*n^2 + 4*n)/20.
G.f.: x*(58*x^8 + 2425*x^7 + 22645*x^6 + 65521*x^5 + 65737*x^4 + 22579*x^3 + 2407*x^2 + 67*x + 1)/(1-x)^11. [Colin Barker, Jun 12 2012]
