Index entries for linear recurrences with constant coefficients, signature (42,-591,2828,-591,42,-1). FORMULA The Belyi function is -108*(z^4+1)^4*z^4/(z^8-14*z^4+1)^3. G.f.: x*(1+x)^4 / (1-14*x+x^2)^3. - Colin Barker, Jan 12 2016 MATHEMATICA LinearRecurrence[{42, -591, 2828, -591, 42, -1}, {0, 1, 46, 1347, 32220, 686661}, 30] (* Harvey P.
