COMMENTS
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."

FORMULA
a(n) = 17*n^3 - 62*n^2 + 71*n + 17.
G.f.: (17 - 25*x - 23*x^2 + 133*x^3)/(1-x)^4. - Colin Barker, Mar 11 2013
