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.

\(f(q)\) \(=\) \( q + (\zeta_{12}^{3} - \zeta_{12}^{2} + \zeta_{12}) q^{3} + \zeta_{12}^{3} q^{5} - 3 \zeta_{12} q^{7} + ( - 4 \zeta_{12}^{3} + \zeta_{12}^{2} + \cdots - 1) q^{9} +O(q^{10}) \) Copy content Toggle raw display \( q + (\zeta_{12}^{3} - \zeta_{12}^{2} + \zeta_{12}) q^{3} + \zeta_{12}^{3} q^{5} - 3 \zeta_{12} q^{7} + ( - 4 \zeta_{12}^{3} + \zeta_{12}^{2} + \cdots - 1) q^{9} + \cdots + ( - 3 \zeta_{12}^{3} + 12 \zeta_{12}^{2} - 6) q^{99} +O(q^{100}) \) Copy content Toggle raw display
