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.

\(f(q)\) \(=\) \( q + \beta q^{3} + (\beta - 1) q^{5} - q^{7} + \beta q^{9} - 4 q^{11} + 2 \beta q^{13} + 3 q^{15} - q^{17} + ( - 2 \beta - 4) q^{19} - \beta q^{21} + 4 q^{23} + ( - \beta - 1) q^{25} + ( - 2 \beta + 3) q^{27} + \cdots - 4 \beta q^{99} +O(q^{100}) \) Copy content Toggle raw display
