%H <a href="/index/Rec#order_05">Index entries for linear recurrences with constant coefficients</a>, signature (2, -1, 1, -2, 1).
%F From _Chai Wah Wu_, Feb 03 2021: (Start)
%F a(n) = 2*a(n-1) - a(n-2) + a(n-3) - 2*a(n-4) + a(n-5) for n > 8.
%F G.f.: (2*x^8 - 2*x^6 - 3*x^4 - 3*x^3 - 4*x^2 - 3*x - 1)/((x - 1)^3*(x^2 + x + 1)). (End)
