$q$-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.

\(f(q)\) \(=\) \( q + 3 \zeta_{6} q^{5} + ( 1 - \zeta_{6} ) q^{7} +O(q^{10})\) \( q + 3 \zeta_{6} q^{5} + ( 1 - \zeta_{6} ) q^{7} + ( 3 - 3 \zeta_{6} ) q^{11} + \zeta_{6} q^{13} -6 q^{17} -4 q^{19} -3 \zeta_{6} q^{23} + ( -4 + 4 \zeta_{6} ) q^{25} + ( 3 - 3 \zeta_{6} ) q^{29} -5 \zeta_{6} q^{31} + 3 q^{35} + 2 q^{37} + 3 \zeta_{6} q^{41} + ( 1 - \zeta_{6} ) q^{43} + ( -9 + 9 \zeta_{6} ) q^{47} + 6 \zeta_{6} q^{49} + 6 q^{53} + 9 q^{55} -3 \zeta_{6} q^{59} + ( 13 - 13 \zeta_{6} ) q^{61} + ( -3 + 3 \zeta_{6} ) q^{65} + 7 \zeta_{6} q^{67} + 12 q^{71} -10 q^{73} -3 \zeta_{6} q^{77} + ( -11 + 11 \zeta_{6} ) q^{79} + ( -9 + 9 \zeta_{6} ) q^{83} -18 \zeta_{6} q^{85} -6 q^{89} + q^{91} -12 \zeta_{6} q^{95} + ( -11 + 11 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + 3q^{5} + q^{7} + O(q^{10}) \) \( 2q + 3q^{5} + q^{7} + 3q^{11} + q^{13} - 12q^{17} - 8q^{19} - 3q^{23} - 4q^{25} + 3q^{29} - 5q^{31} + 6q^{35} + 4q^{37} + 3q^{41} + q^{43} - 9q^{47} + 6q^{49} + 12q^{53} + 18q^{55} - 3q^{59} + 13q^{61} - 3q^{65} + 7q^{67} + 24q^{71} - 20q^{73} - 3q^{77} - 11q^{79} - 9q^{83} - 18q^{85} - 12q^{89} + 2q^{91} - 12q^{95} - 11q^{97} + O(q^{100}) \)
