## $q$-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.

 $$f(q)$$ $$=$$ $$q + \beta_{3} q^{2} - q^{4} -\beta_{3} q^{8} - q^{9} +O(q^{10})$$ $$q + \beta_{3} q^{2} - q^{4} -\beta_{3} q^{8} - q^{9} -\beta_{1} q^{13} + q^{16} + ( -\beta_{1} - \beta_{3} ) q^{17} -\beta_{3} q^{18} + \beta_{2} q^{26} + ( 1 + \beta_{2} ) q^{29} + \beta_{3} q^{32} + ( 1 + \beta_{2} ) q^{34} + q^{36} + ( -\beta_{1} - \beta_{3} ) q^{37} + \beta_{2} q^{41} - q^{49} + \beta_{1} q^{52} -\beta_{1} q^{53} + ( \beta_{1} + \beta_{3} ) q^{58} + \beta_{2} q^{61} - q^{64} + ( \beta_{1} + \beta_{3} ) q^{68} + \beta_{3} q^{72} -\beta_{1} q^{73} + ( 1 + \beta_{2} ) q^{74} + q^{81} + \beta_{1} q^{82} + ( 1 + \beta_{2} ) q^{89} + ( -\beta_{1} - \beta_{3} ) q^{97} -\beta_{3} q^{98} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$4q - 4q^{4} - 4q^{9} + O(q^{10})$$ $$4q - 4q^{4} - 4q^{9} + 4q^{16} - 2q^{26} + 2q^{29} + 2q^{34} + 4q^{36} - 2q^{41} - 4q^{49} - 2q^{61} - 4q^{64} + 2q^{74} + 4q^{81} + 2q^{89} + O(q^{100})$$

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

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