$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q - 16 q^{19} + 8 q^{25} + 24 q^{31} - 8 q^{49} + 20 q^{61} - 56 q^{79} + 4 q^{85} - 52 q^{91}+O(q^{100}) \) Copy content Toggle raw display
