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.

\(f(q)\) \(=\) \( q + ( - \zeta_{6} + 1) q^{3} + \zeta_{6} q^{5} + ( - \zeta_{6} + 3) q^{7} + 2 \zeta_{6} q^{9} + ( - 2 \zeta_{6} + 2) q^{11} + q^{15} + (4 \zeta_{6} - 4) q^{17} - 2 \zeta_{6} q^{19} + ( - 3 \zeta_{6} + 2) q^{21} + \cdots + 4 q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + q^{3} + q^{5} + 5 q^{7} + 2 q^{9} + 2 q^{11} + 2 q^{15} - 4 q^{17} - 2 q^{19} + q^{21} + q^{23} - q^{25} + 10 q^{27} + 18 q^{29} + 4 q^{31} - 2 q^{33} + 4 q^{35} - 4 q^{37} + 2 q^{41} - 18 q^{43}+ \cdots + 8 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

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