$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 216q + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 216q - 24q^{29} + 36q^{33} + 36q^{41} - 24q^{45} + 12q^{57} + 48q^{65} + 48q^{69} + 48q^{77} + 48q^{81} + 36q^{89} - 144q^{93} - 36q^{97} + O(q^{100}) \)
