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

\(f(q)\) \(=\) \( q + 3 i q^{3} - 6 q^{9} - 2 q^{11} + 6 i q^{13} + 2 i q^{17} + 9 i q^{23} - 9 i q^{27} - 3 q^{29} + 2 q^{31} - 6 i q^{33} + 8 i q^{37} - 18 q^{39} + 5 q^{41} - i q^{43} + 8 i q^{47} - 6 q^{51} - 4 i q^{53} + \cdots + 12 q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - 12 q^{9} - 4 q^{11} - 6 q^{29} + 4 q^{31} - 36 q^{39} + 10 q^{41} - 12 q^{51} + 16 q^{59} + 14 q^{61} - 54 q^{69} + 16 q^{71} - 8 q^{79} + 18 q^{81} - 26 q^{89} + 24 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/4900\mathbb{Z}\right)^\times\).

\(n\) \(101\) \(1177\) \(2451\)
\(\chi(n)\) \(1\) \(-1\) \(1\)

Embeddings

For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.
