$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 4 q^{5} + 12 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q - 4 q^{5} + 12 q^{9} - 4 q^{13} - 24 q^{37} - 48 q^{45} - 24 q^{49} + 88 q^{53} + 36 q^{65} + 20 q^{77} + 16 q^{81} - 56 q^{85} - 40 q^{89} + 24 q^{93}+O(q^{100}) \) Copy content Toggle raw display
