$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 512q + 8q^{3} - 12q^{7} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 512q + 8q^{3} - 12q^{7} - 8q^{10} - 8q^{12} + 8q^{15} + 128q^{16} + 28q^{22} + 32q^{25} + 44q^{27} + 8q^{28} + 24q^{30} + 8q^{31} + 28q^{33} + 176q^{37} + 24q^{42} - 40q^{45} - 24q^{46} + 12q^{48} - 16q^{51} - 40q^{55} + 40q^{57} + 56q^{58} + 12q^{60} - 32q^{61} - 224q^{63} + 32q^{66} + 48q^{67} + 24q^{70} + 40q^{73} - 32q^{75} + 48q^{76} - 76q^{78} - 96q^{81} + 24q^{85} - 80q^{87} - 72q^{88} + 16q^{90} + 80q^{91} - 168q^{93} - 112q^{97} + O(q^{100}) \)
