$q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of a basis $$1,\beta_1,\beta_2,\beta_3$$ for the coefficient ring described below. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + \beta_{1} q^{2} + \beta_{2} q^{4} +O(q^{10})$$ $$q + \beta_{1} q^{2} + \beta_{2} q^{4} + ( -\beta_{1} + \beta_{3} ) q^{11} + ( 1 - \beta_{2} ) q^{16} -2 q^{22} -\beta_{1} q^{23} -\beta_{2} q^{25} + \beta_{3} q^{29} + ( \beta_{1} - \beta_{3} ) q^{32} -\beta_{1} q^{44} -2 \beta_{2} q^{46} -\beta_{3} q^{50} + ( \beta_{1} - \beta_{3} ) q^{53} + ( -2 + 2 \beta_{2} ) q^{58} + q^{64} + 2 \beta_{2} q^{67} -\beta_{3} q^{71} + ( -2 + 2 \beta_{2} ) q^{79} -\beta_{3} q^{92} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q + 2q^{4} + O(q^{10})$$ $$4q + 2q^{4} + 2q^{16} - 8q^{22} - 2q^{25} - 4q^{46} - 4q^{58} + 4q^{64} + 4q^{67} - 4q^{79} + O(q^{100})$$
