Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{16}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\zeta_{16}^{3} + \zeta_{16}) q^{3} + ( - 2 \zeta_{16}^{5} - \zeta_{16}) q^{5} + ( - \zeta_{16}^{7} - \zeta_{16}^{5} + \cdots + 1) q^{7}+ \cdots + (\zeta_{16}^{6} + \cdots + \zeta_{16}^{2}) q^{9}+O(q^{10}) \) Copy content Toggle raw display \( q + (\zeta_{16}^{3} + \zeta_{16}) q^{3} + ( - 2 \zeta_{16}^{5} - \zeta_{16}) q^{5} + ( - \zeta_{16}^{7} - \zeta_{16}^{5} + \cdots + 1) q^{7}+ \cdots + (2 \zeta_{16}^{6} + \cdots + 2 \zeta_{16}^{2}) q^{99}+O(q^{100}) \) Copy content Toggle raw display
