Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = 3\sqrt{305281}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - 64 q^{2} + 4096 q^{4} + ( - 19 \beta + 13787) q^{5} - 117649 q^{7} - 262144 q^{8} + (1216 \beta - 882368) q^{10} + (1749 \beta + 2321077) q^{11} + (17602 \beta - 4678272) q^{13} + 7529536 q^{14} + 16777216 q^{16}+ \cdots - 885842380864 q^{98}+O(q^{100}) \) Copy content Toggle raw display
