$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 32 q - 8 q^{23} + 16 q^{25} + 24 q^{31} - 24 q^{47} + 8 q^{49} + 64 q^{55} - 80 q^{71} + 8 q^{73} - 8 q^{79} + 24 q^{95} - 48 q^{97}+O(q^{100}) \) Copy content Toggle raw display
