$q$-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.

\(f(q)\) \(=\) \( q + (\zeta_{6} - 1) q^{7} + ( - 3 \zeta_{6} + 3) q^{11} - \zeta_{6} q^{13} + 6 q^{17} - 4 q^{19} + 3 \zeta_{6} q^{23} + ( - 3 \zeta_{6} + 3) q^{29} - 5 \zeta_{6} q^{31} - 2 q^{37} + 3 \zeta_{6} q^{41} + \cdots + ( - 11 \zeta_{6} + 11) q^{97} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - q^{7} + 3 q^{11} - q^{13} + 12 q^{17} - 8 q^{19} + 3 q^{23} + 3 q^{29} - 5 q^{31} - 4 q^{37} + 3 q^{41} - q^{43} + 9 q^{47} + 6 q^{49} - 12 q^{53} - 3 q^{59} + 13 q^{61} - 7 q^{67} + 24 q^{71}+ \cdots + 11 q^{97}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/2700\mathbb{Z}\right)^\times\).

\(n\) \(1001\) \(1351\) \(2377\)
\(\chi(n)\) \(-\zeta_{6}\) \(1\) \(1\)

Embeddings

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