Vincenzo Librandi, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (8,-28,56,-70,56,-28,8,-1).
FORMULA
From R. J. Mathar, Dec 16 2009: (Start)
a(n) = 8*a(n-1) -28*a(n-2) +56*a(n-3) -70*a(n-4) +56*a(n-5) -28*a(n-6) +8*a(n-7) -a(n-8).
G.f.: x*(1 + 88*x + 718*x^2 + 1208*x^3 + 473*x^4 + 32*x^5)/(x-1)^8. (End)
