Vincenzo Librandi, Table of n, a(n) for n = 0..2000

Index entries for linear recurrences with constant coefficients, signature (11,-55,165,-330,462,-462,330,-165,55,-11,1).

Formula

From Amiram Eldar, Mar 29 2022: (Start)

a(n) = A016933(n)^10 = A016934(n)^5 = A016937(n)^2.

a(n) = 2^10*A016786(n).

Sum_{n>=0} 1/a(n) = PolyGamma(9, 1/3)/21941965946880. (End)
