$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 88 q - 4 q^{3} + 4 q^{4} - 4 q^{6} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 88 q - 4 q^{3} + 4 q^{4} - 4 q^{6} + 4 q^{10} - 8 q^{12} - 8 q^{13} - 4 q^{15} - 12 q^{16} - 12 q^{18} + 8 q^{19} - 4 q^{21} - 4 q^{22} + 12 q^{24} - 4 q^{27} - 4 q^{28} - 28 q^{30} - 16 q^{31} - 4 q^{33} - 28 q^{34} - 20 q^{36} - 8 q^{37} - 24 q^{39} - 44 q^{40} + 40 q^{42} + 8 q^{45} - 36 q^{46} + 32 q^{48} - 4 q^{51} - 48 q^{52} + 24 q^{54} - 12 q^{57} - 20 q^{58} + 28 q^{60} - 24 q^{61} - 32 q^{63} + 28 q^{64} + 12 q^{66} + 12 q^{69} - 76 q^{70} + 24 q^{72} - 36 q^{75} - 36 q^{76} + 60 q^{78} - 8 q^{81} + 64 q^{82} - 48 q^{84} + 16 q^{85} + 12 q^{87} + 44 q^{88} - 56 q^{90} - 8 q^{91} - 16 q^{93} + 20 q^{94} + 48 q^{96} - 8 q^{97} + 32 q^{99} + O(q^{100}) \)
