$q$-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.

\(f(q)\) \(=\) \( q + ( -2 + 2 \zeta_{6} ) q^{3} -\zeta_{6} q^{9} +O(q^{10})\) \( q + ( -2 + 2 \zeta_{6} ) q^{3} -\zeta_{6} q^{9} -4 q^{13} + ( -6 + 6 \zeta_{6} ) q^{17} + 2 \zeta_{6} q^{19} + ( 5 - 5 \zeta_{6} ) q^{25} -4 q^{27} -6 q^{29} + ( -4 + 4 \zeta_{6} ) q^{31} -2 \zeta_{6} q^{37} + ( 8 - 8 \zeta_{6} ) q^{39} + 6 q^{41} -8 q^{43} -12 \zeta_{6} q^{47} -12 \zeta_{6} q^{51} + ( -6 + 6 \zeta_{6} ) q^{53} -4 q^{57} + ( -6 + 6 \zeta_{6} ) q^{59} -8 \zeta_{6} q^{61} + ( -4 + 4 \zeta_{6} ) q^{67} + ( -2 + 2 \zeta_{6} ) q^{73} + 10 \zeta_{6} q^{75} + 8 \zeta_{6} q^{79} + ( 11 - 11 \zeta_{6} ) q^{81} + 6 q^{83} + ( 12 - 12 \zeta_{6} ) q^{87} + 6 \zeta_{6} q^{89} -8 \zeta_{6} q^{93} -10 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{3} - q^{9} + O(q^{10}) \) \( 2q - 2q^{3} - q^{9} - 8q^{13} - 6q^{17} + 2q^{19} + 5q^{25} - 8q^{27} - 12q^{29} - 4q^{31} - 2q^{37} + 8q^{39} + 12q^{41} - 16q^{43} - 12q^{47} - 12q^{51} - 6q^{53} - 8q^{57} - 6q^{59} - 8q^{61} - 4q^{67} - 2q^{73} + 10q^{75} + 8q^{79} + 11q^{81} + 12q^{83} + 12q^{87} + 6q^{89} - 8q^{93} - 20q^{97} + O(q^{100}) \)

Character values
