$q$-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.

\(f(q)\) \(=\) \( q -18 \zeta_{6} q^{5} +O(q^{10})\) \( q -18 \zeta_{6} q^{5} + ( 36 - 36 \zeta_{6} ) q^{11} -10 q^{13} + ( 18 - 18 \zeta_{6} ) q^{17} + 100 \zeta_{6} q^{19} + 72 \zeta_{6} q^{23} + ( -199 + 199 \zeta_{6} ) q^{25} + 234 q^{29} + ( 16 - 16 \zeta_{6} ) q^{31} + 226 \zeta_{6} q^{37} -90 q^{41} + 452 q^{43} + 432 \zeta_{6} q^{47} + ( 414 - 414 \zeta_{6} ) q^{53} -648 q^{55} + ( -684 + 684 \zeta_{6} ) q^{59} -422 \zeta_{6} q^{61} + 180 \zeta_{6} q^{65} + ( -332 + 332 \zeta_{6} ) q^{67} + 360 q^{71} + ( -26 + 26 \zeta_{6} ) q^{73} -512 \zeta_{6} q^{79} + 1188 q^{83} -324 q^{85} -630 \zeta_{6} q^{89} + ( 1800 - 1800 \zeta_{6} ) q^{95} -1054 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 18q^{5} + O(q^{10}) \) \( 2q - 18q^{5} + 36q^{11} - 20q^{13} + 18q^{17} + 100q^{19} + 72q^{23} - 199q^{25} + 468q^{29} + 16q^{31} + 226q^{37} - 180q^{41} + 904q^{43} + 432q^{47} + 414q^{53} - 1296q^{55} - 684q^{59} - 422q^{61} + 180q^{65} - 332q^{67} + 720q^{71} - 26q^{73} - 512q^{79} + 2376q^{83} - 648q^{85} - 630q^{89} + 1800q^{95} - 2108q^{97} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1764\mathbb{Z}\right)^\times\).
