## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = \sqrt{3}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q -\beta q^{3} - q^{5} + 2 q^{9} +O(q^{10})$$ $$q -\beta q^{3} - q^{5} + 2 q^{9} + \beta q^{15} -\beta q^{23} + q^{25} -\beta q^{27} - q^{29} + q^{41} -\beta q^{43} -2 q^{45} + q^{61} + \beta q^{67} + 3 q^{69} -\beta q^{75} + q^{81} + \beta q^{83} + \beta q^{87} - q^{89} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 2q^{5} + 4q^{9} + O(q^{10})$$ $$2q - 2q^{5} + 4q^{9} + 2q^{25} - 2q^{29} + 2q^{41} - 4q^{45} + 2q^{61} + 6q^{69} + 2q^{81} - 2q^{89} + O(q^{100})$$
