$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 48 q - 120 q^{16} + 24 q^{18} + 72 q^{33} - 96 q^{50} - 144 q^{52} + 48 q^{67} - 72 q^{69} + 120 q^{84} + 48 q^{86}+O(q^{100}) \) Copy content Toggle raw display
