$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 40q - 8q^{7} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 40q - 8q^{7} - 4q^{11} + 18q^{14} + 32q^{16} - 4q^{17} + 14q^{19} - 14q^{20} + 4q^{22} - 12q^{23} + 24q^{25} + 32q^{26} + 16q^{28} - 8q^{29} + 14q^{31} + 26q^{32} - 24q^{34} - 26q^{35} + 36q^{37} + 8q^{38} - 30q^{40} + 2q^{41} - 66q^{43} + 32q^{44} - 26q^{46} + 4q^{47} - 14q^{49} + 20q^{50} + 2q^{52} + 8q^{53} - 42q^{55} - 46q^{56} + 24q^{58} - 14q^{59} - 24q^{62} - 28q^{65} - 44q^{67} + 18q^{68} - 4q^{70} + 6q^{71} + 14q^{73} + 20q^{74} - 64q^{76} - 24q^{77} - 20q^{80} + 48q^{82} + 12q^{83} + 2q^{85} + 60q^{86} + 2q^{89} - 14q^{91} - 236q^{92} - 24q^{95} - 62q^{97} + 88q^{98} + O(q^{100}) \)
