$q$-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.

\(f(q)\) \(=\) \( q + \beta_{2} q^{3} + \beta_{1} q^{5} + \beta_{2} q^{7} -4 q^{9} +O(q^{10})\) \( q + \beta_{2} q^{3} + \beta_{1} q^{5} + \beta_{2} q^{7} -4 q^{9} + \beta_{3} q^{11} + 3 \beta_{1} q^{13} -\beta_{3} q^{15} + \beta_{1} q^{17} -7 q^{21} + 5 q^{25} -\beta_{2} q^{27} + 9 q^{29} + 7 \beta_{1} q^{33} -\beta_{3} q^{35} -3 \beta_{3} q^{39} -4 \beta_{1} q^{45} + 3 \beta_{2} q^{47} -7 q^{49} -\beta_{3} q^{51} -5 \beta_{2} q^{55} -4 \beta_{2} q^{63} + 15 q^{65} -2 \beta_{3} q^{71} -6 \beta_{1} q^{73} + 5 \beta_{2} q^{75} + 7 \beta_{1} q^{77} + 3 \beta_{3} q^{79} -5 q^{81} -6 \beta_{2} q^{83} + 5 q^{85} + 9 \beta_{2} q^{87} -3 \beta_{3} q^{91} -3 \beta_{1} q^{97} -4 \beta_{3} q^{99} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 4q - 16q^{9} + O(q^{10}) \) \( 4q - 16q^{9} - 28q^{21} + 20q^{25} + 36q^{29} - 28q^{49} + 60q^{65} - 20q^{81} + 20q^{85} + O(q^{100}) \)

Basis of coefficient ring in terms of a root \(\nu\) of \(x^{4} - x^{3} + 5 x^{2} + 2 x + 4\):

\(\beta_{0}\)\(=\)\( 1 \)
\(\beta_{1}\)\(=\)\((\)\( \nu^{3} + \nu^{2} + \nu + 7 \)\()/3\)
\(\beta_{2}\)\(=\)\((\)\( -2 \nu^{3} + 4 \nu^{2} - 8 \nu + 1 \)\()/3\)
\(\beta_{3}\)\(=\)\( \nu^{3} - \nu^{2} + 7 \nu + 1 \)
\(1\)\(=\)\(\beta_0\)
\(\nu\)\(=\)\((\)\(\beta_{3} + \beta_{2} - \beta_{1} + 1\)\()/4\)
\(\nu^{2}\)\(=\)\((\)\(\beta_{3} + 3 \beta_{2} + 3 \beta_{1} - 9\)\()/4\)
\(\nu^{3}\)\(=\)\((\)\(-\beta_{3} - 2 \beta_{2} + 5 \beta_{1} - 10\)\()/2\)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/2240\mathbb{Z}\right)^\times\).
