%N Expansion of (17-25*x-23*x^2+133*x^3)/(1-x)^4.
%C The old name was "A nested recursion from a cubic prime generating polynomial so that only the ending coefficients are necessary to determine the recursion: f[x_] = 17*x^3 - 62*x^2 + 71*x + 17."
%H <a href="/index/Rec#order_04">Index entries for linear recurrences with constant coefficients</a>, signature (4,-6,4,-1).
%F a(n) = 17*n^3 - 62*n^2 + 71*n + 17.
%F G.f.: (17 - 25*x - 23*x^2 + 133*x^3)/(1-x)^4. - _Colin Barker_, Mar 11 2013
