$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 28 q - 77960422492 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 28 q - 77960422492 q^{9} + 16832040195288 q^{17} + 202504130118092 q^{25} - 55\!\cdots\!92 q^{33}+ \cdots - 19\!\cdots\!16 q^{97}+O(q^{100}) \) Copy content Toggle raw display
