$q$-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
\(\operatorname{Tr}(f)(q) = \) \( 32 q + 192 q^{51} - 144 q^{54} + 208 q^{76} - 256 q^{79} + 16 q^{94}+O(q^{100}) \) Copy content Toggle raw display
