%N A147660 Coefficient expansion of toral of inverse of low ratio (1.6081283851873882) 
               Pisot Polynomial: a(n)=Coefficient_Expansion(1/( -1 + x^2 - x^9 - 
               x^10 + x^11)).
%C A147660 The next 1 + x^2 - x^10 - x^11 + x^12, is not Pisot, so x^11 is the limit 
               that sequence of polynomials below the Golden mean ratio.
