$q$-expansion

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

\(f(q)\) \(=\) \( q - q^{7} +O(q^{10})\) \( q - q^{7} + ( -1 + \zeta_{6}^{2} ) q^{13} + q^{19} + \zeta_{6} q^{25} + ( \zeta_{6} + \zeta_{6}^{2} ) q^{31} + ( \zeta_{6} + \zeta_{6}^{2} ) q^{37} + \zeta_{6}^{2} q^{43} -\zeta_{6} q^{61} + ( -1 + \zeta_{6}^{2} ) q^{67} -\zeta_{6}^{2} q^{73} + ( 1 + \zeta_{6} ) q^{79} + ( 1 - \zeta_{6}^{2} ) q^{91} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{7} + O(q^{10}) \) \( 2q - 2q^{7} - 3q^{13} + 2q^{19} + q^{25} - q^{43} - q^{61} - 3q^{67} + q^{73} + 3q^{79} + 3q^{91} + O(q^{100}) \)
