Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{14}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( - \zeta_{14}^{3} - 1) q^{3} + ( - 2 \zeta_{14}^{5} + 2 \zeta_{14}^{4} + \cdots + 1) q^{5} + ( - \zeta_{14}^{3} + 1) q^{7} + (\zeta_{14}^{5} - \zeta_{14}^{4} + \cdots + \zeta_{14}) q^{9} + ( - 2 \zeta_{14}^{5} + 2 \zeta_{14}^{3} + \cdots - 1) q^{11}+ \cdots + ( - 5 \zeta_{14}^{5} + 6 \zeta_{14}^{4} + \cdots + 3) q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/464\mathbb{Z}\right)^\times\).
