 OFFSET 0,1 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." LINKS Index entries for linear recurrences with constant coefficients, signature (4,-6,4,-1). FORMULA a(n) = 17*n^3 - 62*n^2 + 71*n + 17.
