$q$-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.

\(f(q)\) \(=\) \( q + ( -4 + 4 \zeta_{6} ) q^{5} +O(q^{10})\) \( q + ( -4 + 4 \zeta_{6} ) q^{5} + 3 q^{11} -2 \zeta_{6} q^{13} + ( 2 - 2 \zeta_{6} ) q^{17} + ( 2 - 5 \zeta_{6} ) q^{19} -6 \zeta_{6} q^{23} -11 \zeta_{6} q^{25} -4 \zeta_{6} q^{29} + 10 q^{31} + 2 q^{37} + ( 9 - 9 \zeta_{6} ) q^{41} + ( -4 + 4 \zeta_{6} ) q^{43} + 12 \zeta_{6} q^{47} -7 q^{49} -2 \zeta_{6} q^{53} + ( -12 + 12 \zeta_{6} ) q^{55} + ( 1 - \zeta_{6} ) q^{59} + 8 \zeta_{6} q^{61} + 8 q^{65} + 9 \zeta_{6} q^{67} + ( 6 - 6 \zeta_{6} ) q^{71} + ( 9 - 9 \zeta_{6} ) q^{73} + ( -4 + 4 \zeta_{6} ) q^{79} -5 q^{83} + 8 \zeta_{6} q^{85} -18 \zeta_{6} q^{89} + ( 12 + 8 \zeta_{6} ) q^{95} + ( -1 + \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 4q^{5} + O(q^{10}) \) \( 2q - 4q^{5} + 6q^{11} - 2q^{13} + 2q^{17} - q^{19} - 6q^{23} - 11q^{25} - 4q^{29} + 20q^{31} + 4q^{37} + 9q^{41} - 4q^{43} + 12q^{47} - 14q^{49} - 2q^{53} - 12q^{55} + q^{59} + 8q^{61} + 16q^{65} + 9q^{67} + 6q^{71} + 9q^{73} - 4q^{79} - 10q^{83} + 8q^{85} - 18q^{89} + 32q^{95} - q^{97} + O(q^{100}) \)
