Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{26}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \zeta_{26} q^{2} + ( - \zeta_{26}^{10} - \zeta_{26}^{7} + 1) q^{3} + \zeta_{26}^{2} q^{4} - \zeta_{26}^{9} q^{5} + ( - \zeta_{26}^{11} + \cdots + \zeta_{26}) q^{6} + ( - \zeta_{26}^{11} + \cdots + \zeta_{26}^{2}) q^{7} + \cdots + (4 \zeta_{26}^{11} - 2 \zeta_{26}^{9} + \cdots + 2) q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/790\mathbb{Z}\right)^\times\).
