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.

\(f(q)\) \(=\) \( q + ( - \beta_{2} - 1) q^{3} + ( - 2 \beta_{2} + \beta_1 + 49) q^{5} + (\beta_{2} + 7 \beta_1 + 8) q^{7} + ( - 14 \beta_{2} + 15 \beta_1 + 304) q^{9} + ( - \beta_{2} + 14 \beta_1 + 65) q^{11} + (2 \beta_{2} + 11 \beta_1 + 109) q^{13}+ \cdots + (2133 \beta_{2} + 1854 \beta_1 + 84267) q^{99}+O(q^{100}) \) Copy content Toggle raw display
