$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(i = \sqrt{-1}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + i q^{7} +O(q^{10})\) \( q + i q^{7} -6 q^{11} + 5 i q^{13} -6 i q^{17} -5 q^{19} + 6 i q^{23} -6 q^{29} - q^{31} -2 i q^{37} -i q^{43} + 6 i q^{47} + 6 q^{49} + 12 i q^{53} -6 q^{59} -13 q^{61} -11 i q^{67} + 2 i q^{73} -6 i q^{77} -8 q^{79} + 6 i q^{83} -5 q^{91} + 7 i q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q - 12q^{11} - 10q^{19} - 12q^{29} - 2q^{31} + 12q^{49} - 12q^{59} - 26q^{61} - 16q^{79} - 10q^{91} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/900\mathbb{Z}\right)^\times\).

\(n\) \(101\) \(451\) \(577\)
\(\chi(n)\) \(1\) \(1\) \(-1\)
