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).
FORMULA
Sum_{n>=0} 1/a(n) = 691*Pi^12/638668800. - Amiram Eldar, Oct 11 2020
Product_{n>=1} (1 - 1/a(n)) = Pi*cosh(Pi/2)*cosh(sqrt(3)*Pi/2)*(cos(sqrt(3)*Pi/2) + cosh(Pi/2))/96. - Amiram Eldar, Jan 28 2021
