Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{3} + \beta_1 q^{7} + q^{9} + 2 q^{11} - \beta_1 q^{13} + ( - \beta_{2} - 1) q^{17} + 4 q^{19} - \beta_1 q^{21} + (\beta_{2} + 1) q^{23} - q^{27} + ( - \beta_{2} - \beta_1 + 1) q^{29} - q^{31}+ \cdots + 2 q^{99}+O(q^{100}) \) Copy content Toggle raw display
