$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 648q + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 648q + 18q^{12} + 42q^{18} + 42q^{20} - 48q^{30} - 30q^{32} + 60q^{33} + 60q^{41} - 30q^{42} - 144q^{44} - 18q^{48} - 156q^{50} + 54q^{52} - 12q^{57} + 54q^{58} - 186q^{60} - 24q^{65} - 186q^{66} - 78q^{68} - 42q^{72} - 24q^{81} - 30q^{86} - 36q^{89} + 198q^{90} + 114q^{92} - 144q^{93} - 54q^{94} + 156q^{96} + 36q^{97} + O(q^{100}) \)
