%H <a href="/index/Rec#order_12">Index entries for linear recurrences with constant coefficients</a>, signature (1,0,0,0,0,0,0,0,0,0,1,-1).

%F From _Matthew House_, Feb 13 2017: (Start)

%F G.f.: (x + x^2 + x^3 + x^4 + x^5 + x^6 + x^7 + x^8 + x^9 + x^10 + 90*x^11)/(1 - x - x^11 + x^12).

%F a(n) = a(n-1) + a(n-11) - a(n-12). (End)

%Y Cf. A049872.
