## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = \frac{1}{2}(1 + \sqrt{17})$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + \beta q^{2} + (\beta - 1) q^{3} + (\beta + 2) q^{4} + q^{5} + 4 q^{6} + q^{7} + (\beta + 4) q^{8} + ( - \beta + 2) q^{9}+O(q^{10})$$ q + b * q^2 + (b - 1) * q^3 + (b + 2) * q^4 + q^5 + 4 * q^6 + q^7 + (b + 4) * q^8 + (-b + 2) * q^9 $$q + \beta q^{2} + (\beta -
