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

\(f(q)\) \(=\) \( q + 3 i q^{3} - 9 q^{9}+O(q^{10}) \) Copy content Toggle raw display \( q + 3 i q^{3} - 9 q^{9} + 14 i q^{17} - 22 q^{19} - 34 i q^{23} - 27 i q^{27} - 2 q^{31} - 14 i q^{47} - 49 q^{49} - 42 q^{51} - 86 i q^{53} - 66 i q^{57} - 118 q^{61} + 102 q^{69} + 98 q^{79} + 81 q^{81} - 154 i q^{83} - 6 i q^{93} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1200\mathbb{Z}\right)^\times\).

\(\chi(n)\) \(-1\) \(1\) \(1\) \(1\)

Embeddings

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