G. C. Greubel, Table of n, a(n) for n = 0..1000

Index entries for linear recurrences with constant coefficients, signature (1,0,0,0,0,0,0,-1,1). [R. J. Mathar, Apr 20 2010]

FORMULA

From R. J. Mathar, Apr 20 2010: (Start)

a(n) = a(n-1) - a(n-8) + a(n-9).

G.f.: ( -1-5*x+4*x^2-10*x^3+8*x^4-3*x^5-x^6-6*x^7-3*x^8 ) / ( (x-1)*(1+x^8) ). (End)

a(n) = a(n-16). - G. C. Greubel, Mar 18 2016

MATHEMATICA

PowerMod[6, Range[0, 50], 17] (* G. C. Greubel, Mar 18 2016 *)
