%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.
%F A147660 a(n)=Coefficient_Expansion(1/( -1 + x^2 - x^9 - x^10 + x^11)).
%t A147660 f[x_] = -1 + x^2 - x^9 - x^10 + x^11; g[x] = ExpandAll[x^11*f[1/x]];

50}]
