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.

\(f(q)\) \(=\) \( q + 3 q^{3} + (\beta_1 + 3) q^{7} + 9 q^{9} + (\beta_{2} - 1) q^{11} + (\beta_{2} + \beta_1 - 2) q^{13} + (\beta_{2} - 2 \beta_1 + 7) q^{17} + (\beta_{2} - 2 \beta_1 + 14) q^{19} + (3 \beta_1 + 9) q^{21}+ \cdots + (9 \beta_{2} - 9) q^{99}+O(q^{100}) \) Copy content Toggle raw display
