$q$-expansion

The \(q\)-expansion and trace form are shown below.

\(f(q)\) \(=\) \( q -\zeta_{6}^{2} q^{4} +O(q^{10})\) \( q -\zeta_{6}^{2} q^{4} -\zeta_{6} q^{16} + \zeta_{6}^{2} q^{25} + 2 \zeta_{6} q^{37} -2 q^{43} - q^{64} + 2 \zeta_{6}^{2} q^{67} -2 \zeta_{6} q^{79} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + q^{4} + O(q^{10}) \) \( 2q + q^{4} - q^{16} - q^{25} + 2q^{37} - 4q^{43} - 2q^{64} - 2q^{67} - 2q^{79} + O(q^{100}) \)
