$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 36q + q^{2} - 9q^{4} + 4q^{5} - 6q^{7} + 15q^{8} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 36q + q^{2} - 9q^{4} + 4q^{5} - 6q^{7} + 15q^{8} + 10q^{10} + 7q^{11} - 12q^{13} + q^{14} - 3q^{16} + 3q^{17} + 6q^{19} - 25q^{20} - 21q^{22} + 20q^{23} - 2q^{25} - 6q^{26} - q^{28} + 22q^{29} + 16q^{31} - 26q^{32} + 6q^{34} + 9q^{35} + 32q^{37} - 17q^{38} - 21q^{40} + 5q^{41} - 34q^{43} - 2q^{44} - 32q^{46} + 7q^{47} + 20q^{49} - 236q^{50} + 20q^{52} + 32q^{53} - 17q^{55} + 39q^{56} - 53q^{58} + q^{59} + 14q^{61} + 60q^{62} - 21q^{64} + 39q^{65} - 22q^{67} + 110q^{68} - 40q^{70} - 36q^{71} - 11q^{73} + 46q^{74} - 101q^{76} + 17q^{77} - 14q^{79} + 112q^{80} + 2q^{82} - 12q^{83} - 44q^{85} - 184q^{86} + 204q^{88} - 12q^{89} - 16q^{91} + 105q^{92} - 5q^{94} - 18q^{95} + 172q^{97} - q^{98} + O(q^{100}) \)
