Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{5}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - 2 q^{2} + 4 q^{4} + 5 q^{5} + ( - \beta - 5) q^{7} - 8 q^{8} - 10 q^{10} + (3 \beta - 1) q^{11} + (21 \beta + 31) q^{13} + (2 \beta + 10) q^{14} + 16 q^{16} + (34 \beta + 32) q^{17} - 19 q^{19} + 20 q^{20}+ \cdots + ( - 20 \beta + 626) q^{98}+O(q^{100}) \) Copy content Toggle raw display
