Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{6}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (2 \zeta_{6} - 2) q^{7} - \zeta_{6} q^{13} + 6 q^{17} + 2 q^{19} + ( - 5 \zeta_{6} + 5) q^{25} + (6 \zeta_{6} - 6) q^{29} - 2 \zeta_{6} q^{31} + 2 q^{37} - 12 \zeta_{6} q^{41} + ( - 4 \zeta_{6} + 4) q^{43} + \cdots + ( - 10 \zeta_{6} + 10) q^{97} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/4212\mathbb{Z}\right)^\times\).

\(n\) \(2107\) \(3485\) \(3889\)
\(\chi(n)\) \(1\) \(-\zeta_{6}\) \(1\)
