Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{13})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( - \beta - 1) q^{5} + q^{7} + (\beta - 2) q^{11} - q^{13} + (3 \beta - 3) q^{17} + 3 \beta q^{19} + ( - \beta - 4) q^{23} + (3 \beta - 1) q^{25} + ( - 4 \beta - 1) q^{29} - 2 q^{31} + ( - \beta - 1) q^{35}+ \cdots + 8 q^{97}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 3 q^{5} + 2 q^{7} - 3 q^{11} - 2 q^{13} - 3 q^{17} + 3 q^{19} - 9 q^{23} + q^{25} - 6 q^{29} - 4 q^{31} - 3 q^{35} - 6 q^{41} + 5 q^{43} - 9 q^{47} - 12 q^{49} - 3 q^{53} - 2 q^{55} - 12 q^{59} - 4 q^{61}+ \cdots + 16 q^{97}+O(q^{100}) \) Copy content Toggle raw display
