Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{3}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + q^{4} - \beta q^{7} +O(q^{10}) \) Copy content Toggle raw display \( q + q^{4} - \beta q^{7} + \beta q^{13} + q^{16} + q^{25} - \beta q^{28} + q^{31} - 2 q^{37} + 2 q^{49} + \beta q^{52} + q^{64} + q^{67} + \beta q^{73} + \beta q^{79} - 3 q^{91} - q^{97} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3267\mathbb{Z}\right)^\times\).

\(n\) \(244\) \(3026\)
\(\chi(n)\) \(1\) \(-1\)

Embeddings

For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.
