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

Index entries for linear recurrences with constant coefficients, signature (9,-36,84,-126,126,-84,36,-9,1).

Formula

From Wesley Ivan Hurt, Oct 31 2014: (Start)

G.f.: 256*(65536 + 42456897*x + 1090727863*x^2 + 5245638469*x^3 + 6743985795*x^4 + 2426203459*x^5 + 199242373*x^6 + 1679607*x^7 + x^8)/(1 - x)^9.

a(n) = 9*a(n-1)-36*a(n-2)+84*a(n-3)-126*a(n-4)+126*a(n-5)-84*a(n-6)+36*a(n-7)-9*a(n-8)+a(n-9).

a(n) = (10*n+8)^8 = A001016(A017365(n)). (End)
