$q$-expansion

gp: mfcoefs(f, 20)
 

Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{6}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( - \zeta_{6} + 1) q^{3} + \zeta_{6} q^{5} + (\zeta_{6} - 3) q^{7} + 2 \zeta_{6} q^{9} + ( - 6 \zeta_{6} + 6) q^{11} + 2 q^{13} + q^{15} + ( - 6 \zeta_{6} + 6) q^{17} + 8 \zeta_{6} q^{19} + (3 \zeta_{6} - 2) q^{21}+ \cdots + 12 q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + q^{3} + q^{5} - 5 q^{7} + 2 q^{9} + 6 q^{11} + 4 q^{13} + 2 q^{15} + 6 q^{17} + 8 q^{19} - q^{21} + 3 q^{23} - q^{25} + 10 q^{27} + 6 q^{29} + 2 q^{31} - 6 q^{33} - 4 q^{35} - 8 q^{37} + 2 q^{39}+ \cdots + 24 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

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

\(n\) \(241\) \(337\) \(351\) \(421\)
\(\chi(n)\) \(-\zeta_{6}\) \(1\) \(1\) \(1\)

Embeddings
