FORMULA

b(n) = coefficient expansion of (-x^20 + 228*x^15 - 495*x^10 - 228*x^5 - 1)^3/(1728*x^5*(x^10 + 11*x^5 - 1)^5), a(n) = 1728*b(n)

MATHEMATICA

b = 1728*Flatten[{{1/1728}, Table[Coefficient[Series[(-x^20 + 228*x^15 - 495*x^10 - 228*x^5 - 1)^3/(1728*x^5*(x^10 + 11*x^5 - 1)^5), {x, 0, 30}], x^n], {n, 1, 30}]}]
