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.

\(f(q)\) \(=\) \( q + ( - 8 \zeta_{6} + 16) q^{7}+O(q^{10}) \) Copy content Toggle raw display \( q + ( - 8 \zeta_{6} + 16) q^{7} + (22 \zeta_{6} - 22) q^{13} + (32 \zeta_{6} - 16) q^{19} + 25 \zeta_{6} q^{25} + (24 \zeta_{6} + 24) q^{31} + 26 q^{37} + (48 \zeta_{6} - 96) q^{43} + ( - 143 \zeta_{6} + 143) q^{49} - 74 \zeta_{6} q^{61} + (32 \zeta_{6} + 32) q^{67} + 46 q^{73} + ( - 40 \zeta_{6} + 80) q^{79} + (352 \zeta_{6} - 176) q^{91} + 2 \zeta_{6} q^{97} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1296\mathbb{Z}\right)^\times\).

\(\chi(n)\) \(1\) \(-1\) \(-1 + \zeta_{6}\)

Embeddings

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