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.

\(f(q)\) \(=\) \( q + (\zeta_{24}^{7} - \zeta_{24}^{5} + \zeta_{24}) q^{3} + (\zeta_{24}^{7} + \zeta_{24}^{4} + \cdots - 2) q^{5}+ \cdots + ( - \zeta_{24}^{6} + \cdots - \zeta_{24}^{2}) q^{9}+O(q^{10}) \) Copy content Toggle raw display \( q + (\zeta_{24}^{7} - \zeta_{24}^{5} + \zeta_{24}) q^{3} + (\zeta_{24}^{7} + \zeta_{24}^{4} + \cdots - 2) q^{5}+ \cdots + (6 \zeta_{24}^{6} + 4 \zeta_{24}^{4} - 2) q^{99}+O(q^{100}) \) Copy content Toggle raw display
