$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 128q + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 128q - 16q^{10} + 32q^{16} + 16q^{22} - 32q^{40} - 32q^{46} + 16q^{52} - 32q^{55} - 32q^{58} - 64q^{61} - 48q^{64} - 64q^{67} + 96q^{70} - 32q^{76} + 64q^{79} - 80q^{82} - 80q^{88} + 96q^{91} - 144q^{94} + O(q^{100}) \)
