$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q - 8 q^{9} + 32 q^{13} - 24 q^{21} - 32 q^{25} + 4 q^{33} + 36 q^{37} - 8 q^{45} - 92 q^{49} + 20 q^{61} - 36 q^{69} + 64 q^{73} - 64 q^{81} - 4 q^{85} - 48 q^{93} - 68 q^{97}+O(q^{100}) \) Copy content Toggle raw display
