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.

\(f(q)\) \(=\) \( q + (\beta_{2} + 3) q^{3} - \beta_1 q^{5} + (\beta_1 - 14) q^{7} + (3 \beta_{2} - 3 \beta_1 + 28) q^{9} + ( - 6 \beta_{2} + 3 \beta_1) q^{11} + (\beta_{2} + 3 \beta_1 - 33) q^{13} + (6 \beta_{2} - 5 \beta_1) q^{15}+ \cdots + ( - 312 \beta_{2} + 138 \beta_1 - 1656) q^{99}+O(q^{100}) \) Copy content Toggle raw display
