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) = 4*a(n-1) - 6*a(n-2) + 4*a(n-3) - a(n-4); a(0)=64, a(1)=2744, a(2)=13824, a(3)=39304. - Harvey P. Dale, Oct 01 2014

G.f.: 8*(8 + 311*x + 404*x^2 + 27*x^3)/(x-1)^4. - R. J. Mathar, Mar 20 2018
