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.

\(f(q)\) \(=\) \( q + ( - \beta_1 + 22) q^{2} + ( - 7 \beta_{2} - 64 \beta_1 + 5263) q^{4} - 15625 q^{5} + ( - 240 \beta_{2} + 2144 \beta_1 - 166512) q^{7} + ( - 455 \beta_{2} - 5814 \beta_1 + 810835) q^{8} + (15625 \beta_1 - 343750) q^{10}+ \cdots + (1340672256 \beta_{2} + \cdots - 1205767725274) q^{98}+O(q^{100}) \) Copy content Toggle raw display
