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

Index entries for linear recurrences with constant coefficients, signature (4,-6,4,-1).

Formula

a(n) = A000578(A017341(n)). - Michel Marcus, Aug 04 2021

From Wesley Ivan Hurt, Jan 27 2022: (Start)

G.f.: 8*(27+404*x+311*x^2+8*x^3)/(x-1)^4.

a(n) = 4*a(n-1)-6*a(n-2)+4*a(n-3)-a(n-4). (End)
