$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{8}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\)	\(=\)	\( q + \beta_1 q^{2} + \beta_{5} q^{3} + (\beta_{2} + 1) q^{4} + q^{5} - \beta_{8} q^{6} + (\beta_{4} + 1) q^{7} + (\beta_{3} + \beta_1 + 1) q^{8} + (\beta_{7} - \beta_{2} + 1) q^{9}+O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 9 q + 3 q^{2} + 3 q^{3} + 9 q^{4} + 9 q^{5} + 13 q^{7} + 9 q^{8} + 12 q^{9}+O(q^{10}) \)
