$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24q + 6q^{3} - 10q^{5} + 8q^{7} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 24q + 6q^{3} - 10q^{5} + 8q^{7} + 16q^{11} - 8q^{15} + 8q^{17} - 16q^{19} - 10q^{21} - 12q^{23} - 8q^{25} + 6q^{27} + 40q^{29} + 12q^{31} + 10q^{33} + 36q^{35} + 50q^{39} - 4q^{41} + 16q^{45} + 12q^{47} - 30q^{49} + 24q^{51} - 26q^{53} - 20q^{55} + 10q^{57} - 6q^{59} + 30q^{61} - 92q^{63} + 68q^{65} + 22q^{67} - 38q^{69} - 4q^{71} - 4q^{75} - 20q^{77} + 2q^{79} + 28q^{81} - 80q^{83} - 56q^{85} + 10q^{87} - 72q^{89} - 6q^{93} + 40q^{95} - 22q^{97} - 14q^{99} + O(q^{100}) \)
