Vincenzo Librandi, Table of n, a(n) for n = 0..10000

Index entries for linear recurrences with constant coefficients, signature (13,-78,286,-715,1287,-1716,1716,-1287,715,-286,78,-13,1).

From Amiram Eldar, Oct 11 2020: (Start)

Sum_{n>=1} 1/a(n) = 691*Pi^12/2615348736000.

Sum_{n>=1} (-1)^(n+1)/a(n) = 1414477*Pi^12/5356234211328000. (End)
