$q$-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
\(\operatorname{Tr}(f)(q) = \) \( 32 q + 4 q^{11} - 8 q^{19} - 4 q^{25} + 24 q^{31} - 10 q^{35} + 12 q^{41} + 36 q^{49} - 12 q^{59} - 40 q^{61} - 44 q^{65} - 36 q^{71} - 8 q^{79} - 14 q^{85} + 24 q^{89} - 60 q^{91} - 48 q^{95}+O(q^{100}) \) Copy content Toggle raw display
