Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{20}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{20}^{7} - 2 \zeta_{20}^{5} - 2 \zeta_{20}) q^{2} + 4 \zeta_{20} q^{3} + (4 \zeta_{20}^{6} + \cdots + 4 \zeta_{20}^{2}) q^{4} + ( - 4 \zeta_{20}^{6} - 4 \zeta_{20}^{4} + \cdots - 4) q^{6}+ \cdots + (21 \zeta_{20}^{6} - 84 \zeta_{20}^{4} + \cdots - 70) q^{99}+O(q^{100}) \) Copy content Toggle raw display
