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.

\(f(q)\) \(=\) \( q + ( - 9 \zeta_{6} + 9) q^{3} - 69 \zeta_{6} q^{5} - 81 \zeta_{6} q^{9} + (123 \zeta_{6} - 123) q^{11} + 4 q^{13} - 621 q^{15} + ( - 1776 \zeta_{6} + 1776) q^{17} - 1396 \zeta_{6} q^{19} + 1536 \zeta_{6} q^{23} + \cdots + 9963 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/588\mathbb{Z}\right)^\times\).
