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.

 $$f(q)$$ $$=$$ $$q -\beta_{1} q^{3} + \beta_{3} q^{7} + \beta_{2} q^{9} +O(q^{10})$$ $$q -\beta_{1} q^{3} + \beta_{3} q^{7} + \beta_{2} q^{9} -\beta_{3} q^{11} -\beta_{2} q^{13} + q^{17} -\beta_{1} q^{19} + \beta_{2} q^{21} -\beta_{3} q^{27} - q^{29} + ( -\beta_{1} - \beta_{3} ) q^{31} -\beta_{2} q^{33} + ( -\beta_{1} + \beta_{3} ) q^{39} + q^{41} + \beta_{3} q^{43} + ( \beta_{1} + \beta_{3} ) q^{47} -\beta_{1} q^{51} + ( 1 + \beta_{2} ) q^{53} + ( -1 + \beta_{2} ) q^{57} + ( \beta_{1} + \beta_{3} ) q^{59} + \beta_{2} q^{61} + \beta_{1} q^{63} + ( -\beta_{1} - \beta_{3} ) q^{67} -\beta_{3} q^{71} + ( 1 + \beta_{2} ) q^{73} + q^{77} -\beta_{3} q^{79} + \beta_{1} q^{87} -\beta_{1} q^{91} - q^{93} + ( -1 - \beta_{2} ) q^{97} -\beta_{1} q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q - 2q^{9} + O(q^{10})$$ $$4q - 2q^{9} + 2q^{13} + 4q^{17} - 2q^{21} - 4q^{29} + 2q^{33} + 4q^{41} + 2q^{53} - 6q^{57} - 2q^{61} + 2q^{73} + 4q^{77} - 4q^{93} - 2q^{97} + O(q^{100})$$

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

 $$\beta_{0}$$ $$=$$ $$1$$ $$\beta_{1}$$ $$=$$ $$\nu$$ $$\beta_{2}$$ $$=$$ $$\nu^{2} + 1$$ $$\beta_{3}$$ $$=$$ $$\nu^{3} + 2 \nu$$
 $$1$$ $$=$$ $$\beta_0$$ $$\nu$$ $$=$$ $$\beta_{1}$$ $$\nu^{2}$$ $$=$$ $$\beta_{2} - 1$$ $$\nu^{3}$$ $$=$$ $$\beta_{3} - 2 \beta_{1}$$
