Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{18}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{18}^{4} - \zeta_{18}) q^{2} - \zeta_{18} q^{3} - \zeta_{18}^{5} q^{4} + ( - \zeta_{18}^{5} + \zeta_{18}^{2}) q^{6} + ( - 4 \zeta_{18}^{3} + 4) q^{7} + \zeta_{18}^{3} q^{8} - 2 \zeta_{18}^{2} q^{9} + \cdots + 6 \zeta_{18}^{5} q^{99} +O(q^{100}) \) Copy content Toggle raw display
