$q$-expansion

The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.

\(\operatorname{Tr}(f)(q) = \) \( 96 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 96 q + 656 q^{23} - 1488 q^{31} - 912 q^{35} + 1616 q^{43} - 1488 q^{51} - 1504 q^{53} - 288 q^{55} + 2752 q^{59} + 1824 q^{61} + 1008 q^{63} + 816 q^{67} + 1056 q^{69} + 448 q^{71} - 2208 q^{75} - 3808 q^{77} - 3600 q^{91}+O(q^{100}) \) Copy content Toggle raw display
