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

\(f(q)\) \(=\) \( q + 3 i q^{5} - 3 q^{7}+O(q^{10}) \) Copy content Toggle raw display \( q + 3 i q^{5} - 3 q^{7} - i q^{13} + 7 q^{17} - 4 i q^{19} + 4 q^{23} - 4 q^{25} - 4 i q^{29} + 8 q^{31} - 9 i q^{35} - 7 i q^{37} - 2 q^{41} - i q^{43} - 7 q^{47} + 2 q^{49} + 4 i q^{53} + 14 i q^{59} + 10 i q^{61} + 3 q^{65} + 2 i q^{67} - 3 q^{71} + 14 q^{73} + 10 q^{79} - 14 i q^{83} + 21 i q^{85} + 3 i q^{91} + 12 q^{95} + 8 q^{97} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3744\mathbb{Z}\right)^\times\).

\(n\) \(703\) \(2017\) \(2081\) \(2341\)
\(\chi(n)\) \(1\) \(1\) \(1\) \(-1\)

Embeddings

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