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.

\(f(q)\) \(=\) \( q + (\beta_1 - 1) q^{3} + (\beta_{2} + 3) q^{5} + (\beta_{2} + \beta_1 - 8) q^{7} + ( - 3 \beta_{2} + 2 \beta_1 + 28) q^{9} - 11 q^{11} + (5 \beta_{2} + 5 \beta_1 + 22) q^{13} + ( - 4 \beta_{2} - 3 \beta_1 + 3) q^{15}+ \cdots + (33 \beta_{2} - 22 \beta_1 - 308) q^{99}+O(q^{100}) \) Copy content Toggle raw display
