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

\(f(q)\) \(=\) \( q + (2 i + 1) q^{5} - i q^{7} + 3 q^{9} - 4 i q^{13} + 4 i q^{17} + 4 q^{19} + 8 i q^{23} + (4 i - 3) q^{25} - 2 q^{29} + 8 q^{31} + ( - i + 2) q^{35} - 8 i q^{37} + 6 q^{41} + 8 i q^{43} + (6 i + 3) q^{45} + \cdots - 12 i q^{97} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 2 q^{5} + 6 q^{9} + 8 q^{19} - 6 q^{25} - 4 q^{29} + 16 q^{31} + 4 q^{35} + 12 q^{41} + 6 q^{45} - 2 q^{49} - 8 q^{59} - 12 q^{61} + 16 q^{65} - 24 q^{71} - 8 q^{79} + 18 q^{81} - 16 q^{85} + 20 q^{89}+ \cdots + 8 q^{95}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/560\mathbb{Z}\right)^\times\).

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

Embeddings

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