Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{12}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + 3 \zeta_{12}^{3} q^{3} - 7 \zeta_{12}^{2} q^{5} + 5 \zeta_{12} q^{7} - 9 q^{9} - 13 \zeta_{12} q^{11} - \zeta_{12}^{2} q^{13} + ( - 21 \zeta_{12}^{3} + 21 \zeta_{12}) q^{15} - 24 q^{17} - 24 \zeta_{12}^{3} q^{19} + \cdots + 117 \zeta_{12} q^{99} +O(q^{100}) \) Copy content Toggle raw display

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/288\mathbb{Z}\right)^\times\).
