$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 128q + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 128q - 8q^{10} - 32q^{16} + 32q^{22} + 64q^{40} + 64q^{46} + 88q^{52} - 64q^{55} + 64q^{58} - 32q^{61} - 96q^{64} + 64q^{67} + 48q^{70} + 32q^{76} + 40q^{82} + 40q^{88} - 48q^{91} + 24q^{94} + O(q^{100}) \)
