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.

\(f(q)\) \(=\) \( q + (\beta_{2} + 2) q^{2} + (\beta_{2} + 4 \beta_1 + 12) q^{4} - 25 q^{5} + (10 \beta_{2} - \beta_1 - 37) q^{7} + ( - 13 \beta_{2} + 28 \beta_1) q^{8} + ( - 25 \beta_{2} - 50) q^{10} - 121 q^{11} + (56 \beta_{2} - 4 \beta_1 - 566) q^{13}+ \cdots + ( - 9554 \beta_{2} - 1954 \beta_1 - 65956) q^{98}+O(q^{100}) \) Copy content Toggle raw display
