Michael De Vlieger, Table of n, a(n) for n = 0..10000
Index entries for linear recurrences with constant coefficients, signature (4,-6,4,-1).
FORMULA
G.f.: 8*(1 + 23*x + 23*x^2 + x^3)/(1 - x)^4. - Ilya Gutkovskiy, Jun 21 2016
From Amiram Eldar, Jun 28 2020: (Start)
Sum_{n>=0} 1/a(n) = 7*zeta(3)/64.
Sum_{n>=0} (-1)^n/a(n) = Pi^3/256. (End)
a(n) = 4*a(n-1)-6*a(n-2)+4*a(n-3)-a(n-4). - Wesley Ivan Hurt, Mar 08 2022
