Coefficients of the \(q\)-expansion are expressed in terms of \(i = \sqrt{-1}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + i q^{3} + i q^{5} - q^{9} - 5 i q^{11} - 5 q^{13} - q^{15} - q^{19} + 3 i q^{23} + 4 q^{25} - i q^{27} + 2 i q^{29} + 2 i q^{31} + 5 q^{33} - 8 i q^{37} - 5 i q^{39} + 5 i q^{41} + 9 q^{43} - i q^{45} + \cdots + 5 i q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3468\mathbb{Z}\right)^\times\).

\(n\) \(1157\) \(1735\) \(2893\)
\(\chi(n)\) \(1\) \(1\) \(-1\)

Embeddings

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