Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{2}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + q^{2} + \beta q^{3} - q^{4} + \beta q^{6} - 3 \beta q^{7} - 3 q^{8} - q^{9} - 3 \beta q^{11} - \beta q^{12} - 3 \beta q^{14} - q^{16} - q^{18} - 6 q^{19} - 6 q^{21} - 3 \beta q^{22} + \beta q^{23} + \cdots + 3 \beta q^{99} +O(q^{100}) \) Copy content Toggle raw display
