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.

\(f(q)\) \(=\) \( q + (\beta_{2} - 16752) q^{5} + ( - 3 \beta_{2} - \beta_1 + 4844) q^{7} + (44 \beta_{2} + 16 \beta_1 - 10816) q^{11} + ( - 268 \beta_{2} - 4 \beta_1 + 4307858) q^{13} + (666 \beta_{2} + 320 \beta_1 + 3303072) q^{17}+ \cdots + (63174192 \beta_{2} + \cdots - 566960283378) q^{97}+O(q^{100}) \) Copy content Toggle raw display
