$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{2}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + q^{3} -\beta q^{7} + q^{9} +O(q^{10})\) \( q + q^{3} -\beta q^{7} + q^{9} + \beta q^{13} -\beta q^{21} + q^{25} + q^{27} + \beta q^{31} -\beta q^{37} + \beta q^{39} + q^{49} + \beta q^{61} -\beta q^{63} -2 q^{67} + q^{75} + \beta q^{79} + q^{81} -2 q^{91} + \beta q^{93} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + 2q^{3} + 2q^{9} + O(q^{10}) \) \( 2q + 2q^{3} + 2q^{9} + 2q^{25} + 2q^{27} + 2q^{49} - 4q^{67} + 2q^{75} + 2q^{81} - 4q^{91} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3072\mathbb{Z}\right)^\times\).
