FORMULA

Expansion of 2 + (eta(q)*eta(q^2)/(eta(q^5)*eta(q^10)))^2 in powers of q. - G. C. Greubel, May 05 2018

EXAMPLE

T10C = 1/q - 3*q + 6*q^2 + 2*q^3 + 2*q^4 - 5*q^5 - 16*q^6 + 12*q^7 + 2*q^8 + ...

MATHEMATICA

eta[q_]:= q^(1/24)*QPochhammer[q] a:= CoefficientList[Series[2 + (eta[q]*eta[q^2]/(eta[q^5]*eta[q^10]))^2, {q, 0, 50}], q]; Table[a[[n]], {n, 1, 50}] (* G. C. Greubel, May 05 2018 *)

PROG

(PARI) q='q+O('q^30); Vec(2 + (eta(q)*eta(q^2)/(eta(q^5)*eta(q^10)))^2/q) \\ G. C. Greubel, May 05 2018
