Vincenzo Librandi, Table of n, a(n) for n = 0..2000
Index entries for linear recurrences with constant coefficients, signature (5,-10,10,-5,1).
FORMULA
a(n) = 5*a(n-1) - 10*a(n-2) + 10*a(n-3) - 5*a(n-4) + a(n-5). - Harvey P. Dale, Aug 22 2012
From Amiram Eldar, Mar 29 2022: (Start)
a(n) = 16*A016780(n).
Sum_{n>=0} 1/a(n) = PolyGamma(3, 1/3)/7776. (End)
