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

\(f(q)\) \(=\) \( q - i q^{2} - q^{3} - q^{4} + 2 i q^{5} + i q^{6} + i q^{8} + q^{9} + 2 q^{10} + q^{12} + ( - 2 i + 3) q^{13} - 2 i q^{15} + q^{16} + 2 q^{17} - i q^{18} - 6 i q^{19} - 2 i q^{20} + 4 q^{23} - i q^{24} + \cdots - 12 i q^{97} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3822\mathbb{Z}\right)^\times\).
