$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 48q + q^{2} + 3q^{4} - 6q^{8} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 48q + q^{2} + 3q^{4} - 6q^{8} + 30q^{10} + 9q^{11} + 42q^{14} + 29q^{16} + 5q^{17} - 26q^{19} + 5q^{20} + q^{22} + 4q^{23} - 56q^{25} + 62q^{26} + 7q^{28} - 12q^{29} - 36q^{31} + 14q^{32} - 76q^{34} - 7q^{35} - 20q^{37} + 60q^{38} + 28q^{40} - 41q^{41} + 12q^{43} - 44q^{44} + 16q^{46} - 13q^{47} - 84q^{49} + 12q^{50} + 92q^{52} - 14q^{53} - 38q^{55} - 105q^{56} + 3q^{58} - 57q^{59} + 11q^{61} + 16q^{62} - 110q^{64} - 21q^{65} + 34q^{67} - 22q^{68} - 6q^{71} - 69q^{73} + 90q^{74} - 49q^{76} + 34q^{79} - 55q^{80} + 91q^{82} - 28q^{83} - 44q^{85} + 26q^{86} + 45q^{88} - 11q^{89} - 84q^{92} + 90q^{94} - 150q^{95} + 124q^{97} - 119q^{98} + O(q^{100}) \)
