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

\(f(q)\) \(=\) \( q + q^{2} + q^{4} + (\beta + 2) q^{5} + ( - 2 \beta - 2) q^{7} + q^{8} + (\beta + 2) q^{10} + 4 q^{11} + 2 q^{13} + ( - 2 \beta - 2) q^{14} + q^{16} + ( - 2 \beta + 2) q^{17} + 5 \beta q^{19} + (\beta + 2) q^{20}+ \cdots + (8 \beta + 5) q^{98}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 2 q^{2} + 2 q^{4} + 4 q^{5} - 4 q^{7} + 2 q^{8} + 4 q^{10} + 8 q^{11} + 4 q^{13} - 4 q^{14} + 2 q^{16} + 4 q^{17} + 4 q^{20} + 8 q^{22} + 2 q^{25} + 4 q^{26} - 4 q^{28} + 4 q^{29} - 12 q^{31} + 2 q^{32}+ \cdots + 10 q^{98}+O(q^{100}) \) Copy content Toggle raw display
