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

\(f(q)\) \(=\) \( q + ( - \beta_{3} - \beta_{2} + \beta_1) q^{5} - 3 \beta_{2} q^{9} - 2 \beta_{3} q^{13} - 2 \beta_1 q^{17} + 4 \beta_{2} q^{19} + (4 \beta_{3} - 4 \beta_1) q^{23} + ( - 3 \beta_{2} - 2 \beta_1 + 3) q^{25}+ \cdots - 6 \beta_{3} q^{97}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 4 q - 2 q^{5} - 6 q^{9} + 8 q^{19} + 6 q^{25} - 8 q^{29} + 16 q^{31} + 24 q^{41} - 6 q^{45} - 8 q^{59} + 12 q^{61} - 16 q^{65} + 48 q^{71} - 8 q^{79} - 18 q^{81} - 32 q^{85} - 20 q^{89} + 8 q^{95}+O(q^{100}) \) Copy content Toggle raw display
