Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{24}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \zeta_{24}^{2} q^{2} + \zeta_{24}^{4} q^{4} + ( - 3 \zeta_{24}^{5} + \zeta_{24}) q^{7} + \zeta_{24}^{6} q^{8}+O(q^{10}) \) Copy content Toggle raw display \( q + \zeta_{24}^{2} q^{2} + \zeta_{24}^{4} q^{4} + ( - 3 \zeta_{24}^{5} + \zeta_{24}) q^{7} + \zeta_{24}^{6} q^{8} + (\zeta_{24}^{5} + 2 \zeta_{24}^{4} + \cdots - 4) q^{11}+ \cdots + ( - 5 \zeta_{24}^{4} - 3) q^{98}+O(q^{100}) \) Copy content Toggle raw display
