Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3,\beta_4\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta_1 + 3601146874) q^{2} + (\beta_{3} + 12546134298 \beta_1 + 25\!\cdots\!11) q^{4} + ( - \beta_{4} + 202 \beta_{3} + \cdots + 37\!\cdots\!81) q^{5} + ( - 96732 \beta_{4} + \cdots + 15\!\cdots\!96) q^{7}+ \cdots + (10\!\cdots\!08 \beta_{4} + \cdots - 35\!\cdots\!10) q^{98}+O(q^{100}) \) Copy content Toggle raw display
