$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \beta_{2} q^{5} -\beta_{3} q^{7} +O(q^{10})\) \( q + \beta_{2} q^{5} -\beta_{3} q^{7} -\beta_{1} q^{11} -\beta_{2} q^{17} + 2 \beta_{3} q^{19} -5 \beta_{1} q^{23} -9 q^{25} + 4 \beta_{3} q^{31} -7 \beta_{1} q^{35} -8 q^{37} -\beta_{2} q^{41} + 7 q^{49} + 2 \beta_{3} q^{55} -11 \beta_{1} q^{71} + \beta_{2} q^{77} + 14 q^{85} + 5 \beta_{2} q^{89} + 14 \beta_{1} q^{95} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 4q + O(q^{10}) \) \( 4q - 36q^{25} - 32q^{37} + 28q^{49} + 56q^{85} + O(q^{100}) \)

Basis of coefficient ring in terms of a root \(\nu\) of \(x^{4} + 8 x^{2} + 9\):

\(\beta_{0}\)\(=\)\( 1 \)
\(\beta_{1}\)\(=\)\((\)\( \nu^{3} + 5 \nu \)\()/3\)
\(\beta_{2}\)\(=\)\((\)\( \nu^{3} + 11 \nu \)\()/3\)
\(\beta_{3}\)\(=\)\( \nu^{2} + 4 \)
\(1\)\(=\)\(\beta_0\)
\(\nu\)\(=\)\((\)\(\beta_{2} - \beta_{1}\)\()/2\)
\(\nu^{2}\)\(=\)\(\beta_{3} - 4\)
\(\nu^{3}\)\(=\)\((\)\(-5 \beta_{2} + 11 \beta_{1}\)\()/2\)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/4032\mathbb{Z}\right)^\times\).
