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

\(f(q)\) \(=\) \( q + \beta q^{2} + ( - \beta + 3) q^{5} + ( - \beta + 2) q^{7} - 2 \beta q^{8} + (3 \beta - 2) q^{10} + q^{11} + \beta q^{13} + (2 \beta - 2) q^{14} - 4 q^{16} + ( - 4 \beta + 2) q^{17} + (2 \beta + 4) q^{19} + \cdots + ( - \beta - 8) q^{98} +O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 6 q^{5} + 4 q^{7} - 4 q^{10} + 2 q^{11} - 4 q^{14} - 8 q^{16} + 4 q^{17} + 8 q^{19} + 6 q^{23} + 12 q^{25} + 4 q^{26} - 8 q^{29} - 2 q^{31} - 16 q^{34} + 16 q^{35} - 18 q^{37} + 8 q^{38} + 8 q^{40}+ \cdots - 16 q^{98}+O(q^{100}) \) Copy content Toggle raw display
