Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{24}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{24}^{7} - \zeta_{24}^{5} + \zeta_{24}) q^{5} + (\zeta_{24}^{6} + \zeta_{24}^{4} + \cdots - 2) q^{7} + ( - 3 \zeta_{24}^{7} + \cdots - 3 \zeta_{24}) q^{11} + ( - 4 \zeta_{24}^{6} + \zeta_{24}^{4} + \cdots - 1) q^{13}+ \cdots + ( - 6 \zeta_{24}^{6} + \cdots - 6 \zeta_{24}^{2}) q^{97}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/2592\mathbb{Z}\right)^\times\).
