Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{28}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{28}^{11} - \zeta_{28}^{9} + \cdots - \zeta_{28}) q^{2}+ \cdots + ( - 2 \zeta_{28}^{10} - \zeta_{28}^{6} + \cdots + 1) q^{9}+O(q^{10}) \) Copy content Toggle raw display \( q + (\zeta_{28}^{11} - \zeta_{28}^{9} + \cdots - \zeta_{28}) q^{2}+ \cdots + (\zeta_{28}^{11} + \cdots + \zeta_{28}^{3}) q^{99}+O(q^{100}) \) Copy content Toggle raw display
