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

\(f(q)\) \(=\) \( q + (\beta + 1) q^{2} + q^{3} + (2 \beta + 1) q^{4} + q^{5} + (\beta + 1) q^{6} + (\beta + 3) q^{8} + q^{9} + (\beta + 1) q^{10} + 2 \beta q^{11} + (2 \beta + 1) q^{12} + ( - 2 \beta - 2) q^{13} + q^{15}+ \cdots + 2 \beta q^{99}+O(q^{100}) \) Copy content Toggle raw display
