$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{-7}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q -\beta q^{7} +O(q^{10})\) \( q -\beta q^{7} + 2 \beta q^{11} + 2 \beta q^{23} + 5 q^{25} -2 q^{29} -6 q^{37} -2 \beta q^{43} -7 q^{49} -10 q^{53} + 6 \beta q^{67} + 2 \beta q^{71} + 14 q^{77} + 6 \beta q^{79} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q + 10q^{25} - 4q^{29} - 12q^{37} - 14q^{49} - 20q^{53} + 28q^{77} + O(q^{100}) \)

Character Values

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