Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = 4\sqrt{2}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta - 1) q^{3} - 5 q^{5} + 7 q^{7} + ( - 2 \beta + 6) q^{9} + (8 \beta + 7) q^{11} + (\beta + 25) q^{13} + ( - 5 \beta + 5) q^{15} + (11 \beta - 25) q^{17} + ( - 11 \beta - 18) q^{19} + (7 \beta - 7) q^{21}+ \cdots + (34 \beta - 470) q^{99}+O(q^{100}) \) Copy content Toggle raw display
