$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 216 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q - 216 q^{9} - 600 q^{25} + 928 q^{33} - 160 q^{41} + 1176 q^{49} + 1376 q^{57} - 976 q^{65} + 592 q^{73} - 1736 q^{81} - 176 q^{89} - 5952 q^{97}+O(q^{100}) \) Copy content Toggle raw display
