$q$-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.

\(f(q)\) \(=\) \( q -\zeta_{6} q^{5} +O(q^{10})\) \( q -\zeta_{6} q^{5} + ( 5 - 5 \zeta_{6} ) q^{11} -3 q^{17} -5 q^{19} -6 \zeta_{6} q^{23} + ( -1 + \zeta_{6} ) q^{25} + ( -10 + 10 \zeta_{6} ) q^{29} -2 \zeta_{6} q^{31} + 4 q^{37} -3 \zeta_{6} q^{41} + ( 3 - 3 \zeta_{6} ) q^{43} + ( -4 + 4 \zeta_{6} ) q^{47} + 7 \zeta_{6} q^{49} + 6 q^{53} -5 q^{55} + 3 \zeta_{6} q^{59} + ( -2 + 2 \zeta_{6} ) q^{61} -11 \zeta_{6} q^{67} -14 q^{71} -15 q^{73} + ( 10 - 10 \zeta_{6} ) q^{79} + ( 12 - 12 \zeta_{6} ) q^{83} + 3 \zeta_{6} q^{85} -14 q^{89} + 5 \zeta_{6} q^{95} + ( 13 - 13 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - q^{5} + O(q^{10}) \) \( 2q - q^{5} + 5q^{11} - 6q^{17} - 10q^{19} - 6q^{23} - q^{25} - 10q^{29} - 2q^{31} + 8q^{37} - 3q^{41} + 3q^{43} - 4q^{47} + 7q^{49} + 12q^{53} - 10q^{55} + 3q^{59} - 2q^{61} - 11q^{67} - 28q^{71} - 30q^{73} + 10q^{79} + 12q^{83} + 3q^{85} - 28q^{89} + 5q^{95} + 13q^{97} + O(q^{100}) \)
