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

\(f(q)\) \(=\) \( q + 3 i q^{3} - 4 i q^{7} - 6 q^{9} - 3 q^{11} + 2 i q^{13} - 3 i q^{17} + 7 q^{19} + 12 q^{21} + 6 i q^{23} - 9 i q^{27} + 6 q^{29} + 10 q^{31} - 9 i q^{33} - 6 q^{39} - 11 q^{41} + 4 i q^{43} + 2 i q^{47} + \cdots + 18 q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 12 q^{9} - 6 q^{11} + 14 q^{19} + 24 q^{21} + 12 q^{29} + 20 q^{31} - 12 q^{39} - 22 q^{41} - 18 q^{49} + 18 q^{51} + 8 q^{59} - 16 q^{61} - 36 q^{69} - 4 q^{71} + 24 q^{79} + 18 q^{81} - 6 q^{89}+ \cdots + 36 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3200\mathbb{Z}\right)^\times\).

\(n\) \(901\) \(1151\) \(2177\)
\(\chi(n)\) \(1\) \(1\) \(-1\)

Embeddings

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