Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{6}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \zeta_{6} q^{2} + (2 \zeta_{6} - 2) q^{3} + (\zeta_{6} - 1) q^{4} + 2 q^{6} + ( - 2 \zeta_{6} + 3) q^{7} + q^{8} - \zeta_{6} q^{9} + (3 \zeta_{6} - 3) q^{11} - 2 \zeta_{6} q^{12} + q^{13} + ( - \zeta_{6} - 2) q^{14} + \cdots + 3 q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - q^{2} - 2 q^{3} - q^{4} + 4 q^{6} + 4 q^{7} + 2 q^{8} - q^{9} - 3 q^{11} - 2 q^{12} + 2 q^{13} - 5 q^{14} - q^{16} - 6 q^{17} - q^{18} + q^{19} + 2 q^{21} + 6 q^{22} + 9 q^{23} - 2 q^{24} - q^{26}+ \cdots + 6 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/350\mathbb{Z}\right)^\times\).

\(n\) \(101\) \(127\)
\(\chi(n)\) \(-\zeta_{6}\) \(1\)

Embeddings

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