$q$-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.

\(f(q)\) \(=\) \( q + ( -2 + 2 \zeta_{6} ) q^{5} + ( -1 + 3 \zeta_{6} ) q^{7} +O(q^{10})\) \( q + ( -2 + 2 \zeta_{6} ) q^{5} + ( -1 + 3 \zeta_{6} ) q^{7} + 2 \zeta_{6} q^{11} -3 q^{13} + 8 \zeta_{6} q^{17} + ( 1 - \zeta_{6} ) q^{19} + ( 8 - 8 \zeta_{6} ) q^{23} + \zeta_{6} q^{25} -4 q^{29} -3 \zeta_{6} q^{31} + ( -4 - 2 \zeta_{6} ) q^{35} + ( 1 - \zeta_{6} ) q^{37} -6 q^{41} + 11 q^{43} + ( 6 - 6 \zeta_{6} ) q^{47} + ( -8 + 3 \zeta_{6} ) q^{49} -12 \zeta_{6} q^{53} -4 q^{55} + 4 \zeta_{6} q^{59} + ( 6 - 6 \zeta_{6} ) q^{61} + ( 6 - 6 \zeta_{6} ) q^{65} -13 \zeta_{6} q^{67} + 10 q^{71} + 11 \zeta_{6} q^{73} + ( -6 + 4 \zeta_{6} ) q^{77} + ( 3 - 3 \zeta_{6} ) q^{79} -2 q^{83} -16 q^{85} + ( 3 - 9 \zeta_{6} ) q^{91} + 2 \zeta_{6} q^{95} + 10 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{5} + q^{7} + O(q^{10}) \) \( 2q - 2q^{5} + q^{7} + 2q^{11} - 6q^{13} + 8q^{17} + q^{19} + 8q^{23} + q^{25} - 8q^{29} - 3q^{31} - 10q^{35} + q^{37} - 12q^{41} + 22q^{43} + 6q^{47} - 13q^{49} - 12q^{53} - 8q^{55} + 4q^{59} + 6q^{61} + 6q^{65} - 13q^{67} + 20q^{71} + 11q^{73} - 8q^{77} + 3q^{79} - 4q^{83} - 32q^{85} - 3q^{91} + 2q^{95} + 20q^{97} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/252\mathbb{Z}\right)^\times\).
