$q$-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
\(\operatorname{Tr}(f)(q) = \) \( 32 q - 16 q^{19} + 32 q^{25} - 32 q^{43} - 64 q^{49} + 32 q^{67} - 16 q^{73} + 112 q^{97}+O(q^{100}) \) Copy content Toggle raw display
