Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{12}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{12}^{3} - \zeta_{12}^{2} + \cdots + 2) q^{2}+ \cdots + (\zeta_{12}^{2} - 1) q^{9}+O(q^{10}) \) Copy content Toggle raw display \( q + (\zeta_{12}^{3} - \zeta_{12}^{2} + \cdots + 2) q^{2}+ \cdots + ( - 4 \zeta_{12}^{2} + 2) q^{99}+O(q^{100}) \) Copy content Toggle raw display
