$q$-expansion

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.

\(f(q)\) \(=\) \( q -3 q^{7} +O(q^{10})\) \( q -3 q^{7} + 2 q^{11} -\zeta_{6} q^{13} + ( 4 - 4 \zeta_{6} ) q^{17} + ( -5 + 2 \zeta_{6} ) q^{19} + 4 \zeta_{6} q^{23} + 5 \zeta_{6} q^{25} -7 q^{31} - q^{37} + ( 4 - 4 \zeta_{6} ) q^{41} + ( 1 - \zeta_{6} ) q^{43} + 2 \zeta_{6} q^{47} + 2 q^{49} + 12 \zeta_{6} q^{53} + ( 2 - 2 \zeta_{6} ) q^{59} + \zeta_{6} q^{61} + 13 \zeta_{6} q^{67} + ( -10 + 10 \zeta_{6} ) q^{71} + ( 3 - 3 \zeta_{6} ) q^{73} -6 q^{77} + ( -13 + 13 \zeta_{6} ) q^{79} -8 q^{83} + 18 \zeta_{6} q^{89} + 3 \zeta_{6} q^{91} + ( -2 + 2 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 6q^{7} + O(q^{10}) \) \( 2q - 6q^{7} + 4q^{11} - q^{13} + 4q^{17} - 8q^{19} + 4q^{23} + 5q^{25} - 14q^{31} - 2q^{37} + 4q^{41} + q^{43} + 2q^{47} + 4q^{49} + 12q^{53} + 2q^{59} + q^{61} + 13q^{67} - 10q^{71} + 3q^{73} - 12q^{77} - 13q^{79} - 16q^{83} + 18q^{89} + 3q^{91} - 2q^{97} + O(q^{100}) \)
