Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{36}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{36}^{11} - \zeta_{36}^{7} + \cdots + \zeta_{36}) q^{3}+ \cdots + ( - 2 \zeta_{36}^{10} + \cdots - 2 \zeta_{36}^{2}) q^{9}+O(q^{10}) \) Copy content Toggle raw display \( q + (\zeta_{36}^{11} - \zeta_{36}^{7} + \cdots + \zeta_{36}) q^{3}+ \cdots + ( - 5 \zeta_{36}^{10} + 7 \zeta_{36}^{8} + \cdots + 3) q^{99}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1400\mathbb{Z}\right)^\times\).

\(\chi(n)\) \(1\) \(1\) \(-\zeta_{36}^{6}\) \(-1\)
