$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 96 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 96 q + 4 q^{25} - 40 q^{31} - 48 q^{49} - 24 q^{55} - 40 q^{61} + 40 q^{79} - 60 q^{85} + 64 q^{91}+O(q^{100}) \) Copy content Toggle raw display
