FORMULA
The Belyi function is 1/Belyi function for cube.
From Colin Barker, Jan 12 2016: (Start)
a(n) = 256*(-1)^n*(8*n^3-24*n^2+25*n-9)/3 for n>2.
a(n) = -4*a(n-1)-6*a(n-2)-4*a(n-3)-a(n-4) for n>6.
G.f.: (1-14*x+x^2)^3 / (1+x)^4.
(End)
PROG
(PARI) Vec((1-14*x+x^2)^3/(1+x)^4 + O(x^30)) \\ Colin Barker, Jan 12 2016
