Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{505}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - 2 q^{2} - 3 q^{3} + 4 q^{4} + 5 q^{5} + 6 q^{6} - 8 q^{8} + 9 q^{9} - 10 q^{10} + ( - \beta - 29) q^{11} - 12 q^{12} + ( - 2 \beta - 28) q^{13} - 15 q^{15} + 16 q^{16} + ( - 5 \beta + 5) q^{17} - 18 q^{18}+ \cdots + ( - 9 \beta - 261) q^{99}+O(q^{100}) \) Copy content Toggle raw display
