$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24q - 96q^{4} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 24q - 96q^{4} + 144q^{16} + 624q^{22} + 312q^{25} - 864q^{37} + 1248q^{43} - 3888q^{46} - 7440q^{58} - 3360q^{64} - 2688q^{67} + 480q^{79} + 13248q^{85} - 7248q^{88} + O(q^{100}) \)
