$q$-expansion

comment: 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.

\(f(q)\) \(=\) \( q + (\zeta_{6} - 1) q^{3} + ( - 2 \zeta_{6} + 2) q^{4} + ( - 3 \zeta_{6} + 2) q^{7} - \zeta_{6} q^{9} + ( - 2 \zeta_{6} + 2) q^{11} + 2 \zeta_{6} q^{12} - 3 q^{13} - 4 \zeta_{6} q^{16} + (2 \zeta_{6} - 2) q^{17} + \cdots - 2 q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - q^{3} + 2 q^{4} + q^{7} - q^{9} + 2 q^{11} + 2 q^{12} - 6 q^{13} - 4 q^{16} - 2 q^{17} - 3 q^{19} + 4 q^{21} - q^{23} + 5 q^{25} + 2 q^{27} - 8 q^{28} + 12 q^{29} + 3 q^{31} + 2 q^{33} - 4 q^{36}+ \cdots - 4 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/483\mathbb{Z}\right)^\times\).

\(n\) \(323\) \(346\) \(442\)
\(\chi(n)\) \(1\) \(-\zeta_{6}\) \(1\)

Embeddings
