$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 48q + 13q^{2} - 9q^{4} + 14q^{5} - 14q^{7} + 20q^{8} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 48q + 13q^{2} - 9q^{4} + 14q^{5} - 14q^{7} + 20q^{8} - 14q^{10} + 3q^{11} - 14q^{13} - 21q^{14} - 3q^{16} + 7q^{17} + 21q^{19} - 14q^{20} - 20q^{22} - 15q^{23} - 4q^{25} + 28q^{28} - 12q^{29} + 35q^{31} - 45q^{32} + 70q^{34} + 15q^{37} + 28q^{38} - 42q^{40} + 42q^{41} - 30q^{43} + 50q^{44} - 78q^{46} - 21q^{47} - 70q^{49} - 40q^{50} - 70q^{52} - 11q^{53} - 7q^{55} + 28q^{56} + 16q^{58} + 28q^{59} + 7q^{61} + 28q^{62} - 32q^{64} - 14q^{65} + 11q^{67} - 77q^{68} + 70q^{70} - 19q^{71} + 7q^{73} - 34q^{74} + 119q^{76} - 7q^{77} + 15q^{79} - 70q^{80} - 14q^{82} - 26q^{85} + 33q^{86} - 77q^{88} + 14q^{89} + 84q^{91} + 38q^{92} + 14q^{94} + 61q^{95} + 161q^{98} + O(q^{100}) \)
