$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 54q + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 54q + 9q^{11} + 12q^{17} - 18q^{19} + 12q^{21} + 21q^{27} + 6q^{29} - 36q^{31} - 9q^{33} - 24q^{39} + 3q^{41} + 21q^{43} + 42q^{45} - 18q^{49} - 24q^{51} + 36q^{53} + 72q^{55} + 39q^{57} - 18q^{59} - 18q^{61} + 30q^{63} + 48q^{65} + 27q^{67} + 24q^{69} + 84q^{75} + 36q^{77} - 72q^{79} + 36q^{81} - 6q^{87} + 33q^{89} - 36q^{91} + 72q^{93} - 36q^{95} + 9q^{97} - 120q^{99} + O(q^{100}) \)
