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.

\(f(q)\) \(=\) \( q - \zeta_{6} q^{2} + ( - 9 \zeta_{6} + 9) q^{3} + ( - 31 \zeta_{6} + 31) q^{4} + 34 \zeta_{6} q^{5} - 9 q^{6} - 63 q^{8} - 81 \zeta_{6} q^{9} + ( - 34 \zeta_{6} + 34) q^{10} + ( - 340 \zeta_{6} + 340) q^{11} + \cdots - 27540 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/147\mathbb{Z}\right)^\times\).

\(n\) \(50\) \(52\)
\(\chi(n)\) \(1\) \(-\zeta_{6}\)

Embeddings

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