Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{10}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \zeta_{10}^{3} q^{3} + ( - \zeta_{10}^{3} + 1) q^{5} + (2 \zeta_{10}^{3} + \cdots + 2 \zeta_{10}) q^{7} - \zeta_{10} q^{9} + ( - \zeta_{10}^{3} - 3 \zeta_{10}^{2} + \cdots - 1) q^{11} + (2 \zeta_{10}^{2} + \zeta_{10} + 2) q^{13} + \cdots + (4 \zeta_{10}^{3} - 2 \zeta_{10}^{2} + \cdots - 1) q^{99} +O(q^{100}) \) Copy content Toggle raw display
