$q$-expansion

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.

\(f(q)\) \(=\) \( q + ( - \zeta_{6} + 1) q^{2} + ( - 2 \zeta_{6} + 2) q^{3} - \zeta_{6} q^{4} - 3 q^{5} - 2 \zeta_{6} q^{6} - \zeta_{6} q^{7} - q^{8} - \zeta_{6} q^{9} + (3 \zeta_{6} - 3) q^{10} + ( - 6 \zeta_{6} + 6) q^{11} + \cdots - 6 q^{99} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + q^{2} + 2 q^{3} - q^{4} - 6 q^{5} - 2 q^{6} - q^{7} - 2 q^{8} - q^{9} - 3 q^{10} + 6 q^{11} - 4 q^{12} + 5 q^{13} - 2 q^{14} - 6 q^{15} - q^{16} + 3 q^{17} - 2 q^{18} + 4 q^{19} + 3 q^{20} - 4 q^{21}+ \cdots - 12 q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/182\mathbb{Z}\right)^\times\).

\(n\) \(15\) \(157\)
\(\chi(n)\) \(-\zeta_{6}\) \(1\)

Embeddings

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