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.

\(f(q)\) \(=\) \( q + (2 \zeta_{36}^{10} - \zeta_{36}^{4}) q^{3} + (\zeta_{36}^{11} + \cdots - \zeta_{36}^{3}) q^{7} - 3 \zeta_{36}^{8} q^{9} + (\zeta_{36}^{9} + \cdots + \zeta_{36}^{2}) q^{13} + (3 \zeta_{36}^{10} + \cdots + 2 \zeta_{36}) q^{19} + \cdots + (11 \zeta_{36}^{8} + \cdots + 8 \zeta_{36}) q^{97} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 12 q + 54 q^{27} - 66 q^{37} + 54 q^{39} - 66 q^{49} + 66 q^{91}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/444\mathbb{Z}\right)^\times\).
