Index entries for linear recurrences with constant coefficients, signature (684, -157434, 12527460, -77460495, 130689144, 33211924, -130689144, -77460495, -12527460, -157434, -684, -1).

FORMULA

The Belyi function is 1728*z^5*(z^10-11*z^5-1)^5/(z^20+228*z^15+494*z^10-228*z^5+1)^3.

G.f.: x*(1+11*x-x^2)^5 / (1-228*x+494*x^2+228*x^3+x^4)^3. - Colin Barker, Jan 12 2016

PROG

(PARI) concat(0, Vec(x*(1+11*x-x^2)^5/(1-228*x+494*x^2+228*x^3+x^4)^3 + O(x^20))) \\ Colin Barker, Jan 12 2016
