Vincenzo Librandi, Table of n, a(n) for n = 0..10000
Index entries for linear recurrences with constant coefficients, signature (11,-55,165,-330,462,-462,330,-165,55,-11,1).
FORMULA
G.f.: -1024*x*(1+x)*(x^8 + 1012*x^7 + 46828*x^6 + 408364*x^5 + 901990*x^4 + 408364*x^3 + 46828*x^2 + 1012*x + 1)/(x-1)^11. - R. J. Mathar, Jul 07 2017
From Amiram Eldar, Oct 11 2020: (Start)
Sum_{n>=1} 1/a(n) = Pi^10/95800320.
Sum_{n>=1} (-1)^(n+1)/a(n) = 73*Pi^10/7007109120. (End)
