Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{10}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \zeta_{10}^{3} q^{3} + ( - 3 \zeta_{10}^{3} + 2 \zeta_{10}^{2} + \cdots + 3) q^{5} + ( - 2 \zeta_{10}^{3} + \cdots - 2 \zeta_{10}) q^{7} - \zeta_{10} q^{9} + (\zeta_{10}^{3} + \zeta_{10}^{2} + \cdots - 3) q^{11} + \cdots + ( - 2 \zeta_{10}^{3} + 2 \zeta_{10} + 1) q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 4 q - q^{3} + 5 q^{5} - 7 q^{7} - q^{9} - 11 q^{11} - 5 q^{13} + 2 q^{17} + 12 q^{19} + 8 q^{21} - 8 q^{23} + 10 q^{25} - q^{27} + 6 q^{29} - 10 q^{31} + 9 q^{33} - 5 q^{35} - 3 q^{37} - 5 q^{39} - 7 q^{41}+ \cdots + 4 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/264\mathbb{Z}\right)^\times\).

\(\chi(n)\) \(1\) \(1\) \(\zeta_{10}^{2}\) \(1\)
