$q$-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.

 $$f(q)$$ $$=$$ $$q -\beta_{2} q^{5} +O(q^{10})$$ $$q -\beta_{2} q^{5} + \beta_{2} q^{11} + 2 \beta_{1} q^{13} -4 q^{19} + 2 \beta_{2} q^{23} -10 q^{25} -\beta_{3} q^{29} + q^{31} + 4 q^{37} -2 \beta_{2} q^{41} -4 \beta_{1} q^{43} + 2 \beta_{3} q^{47} + \beta_{3} q^{53} + 15 q^{55} + \beta_{3} q^{59} -6 \beta_{1} q^{61} + 2 \beta_{3} q^{65} -4 \beta_{1} q^{67} -2 \beta_{2} q^{71} -4 \beta_{1} q^{73} -7 \beta_{1} q^{79} + \beta_{3} q^{83} -2 \beta_{2} q^{89} + 4 \beta_{2} q^{95} -3 \beta_{1} q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q + O(q^{10})$$ $$4q - 16q^{19} - 40q^{25} + 4q^{31} + 16q^{37} + 60q^{55} + O(q^{100})$$

Basis of coefficient ring in terms of a root $$\nu$$ of $$x^{4} - x^{3} + 2 x^{2} + x + 1$$:

 $$\beta_{0}$$ $$=$$ $$1$$ $$\beta_{1}$$ $$=$$ $$-\nu^{3} + 2 \nu^{2} - 2 \nu$$ $$\beta_{2}$$ $$=$$ $$2 \nu^{3} - 2 \nu^{2} + 6 \nu + 1$$ $$\beta_{3}$$ $$=$$ $$-3 \nu^{3} - 6$$
 $$1$$ $$=$$ $$\beta_0$$ $$\nu$$ $$=$$ $$($$$$\beta_{3} + 3 \beta_{2} + 3 \beta_{1} + 3$$$$)/12$$ $$\nu^{2}$$ $$=$$ $$($$$$-\beta_{3} + 3 \beta_{2} + 9 \beta_{1} - 9$$$$)/12$$ $$\nu^{3}$$ $$=$$ $$($$$$-\beta_{3} - 6$$$$)/3$$
