Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \frac{1}{2}(1 + \sqrt{61})\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{2} - q^{3} + q^{4} + \beta q^{5} + q^{6} + q^{7} - q^{8} - 2 q^{9} - \beta q^{10} - \beta q^{11} - q^{12} + (\beta - 2) q^{13} - q^{14} - \beta q^{15} + q^{16} + ( - \beta + 3) q^{17} + 2 q^{18} + \cdots + 2 \beta q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 2 q^{2} - 2 q^{3} + 2 q^{4} + q^{5} + 2 q^{6} + 2 q^{7} - 2 q^{8} - 4 q^{9} - q^{10} - q^{11} - 2 q^{12} - 3 q^{13} - 2 q^{14} - q^{15} + 2 q^{16} + 5 q^{17} + 4 q^{18} - 5 q^{19} + q^{20} - 2 q^{21}+ \cdots + 2 q^{99}+O(q^{100}) \) Copy content Toggle raw display
