Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (0,0,0,0,0,0,0,155234,0,0,0,0,0,0,0,-1).
FORMULA
a(n) = 155234*a(n-8) - a(n-16) for n>15. [Bruno Berselli, Nov 06 2013]
G.f.: -(x^15 -18*x^14 +19*x^13 -75*x^12 +394*x^11 -3621*x^10 +18499*x^9 -59118*x^8 -77617*x^7 -59118*x^6 -18499*x^5 -3621*x^4 -394*x^3 -75*x^2 -19*x -18) / ((x^8 -394*x^4 +1)*(x^8 +394*x^4 +1)). - Colin Barker, Dec 28 2013
