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
From R. J. Mathar, Jun 24 2009: (Start)
G.f.: 64*(8 + 93*x + 60*x^2 + x^3)/(-1+x)^4.
a(n) = 64*A016791(n). (End)
a(n) = 4*a(n-1) - 6*a(n-2) + 4*a(n-3) - a(n-4); a(0)=512, a(1)=8000, a(2)=32768, a(3)=85184. - Harvey P. Dale, Dec 14 2015
