$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 40 q - 16 q^{9} + 24 q^{13} + 8 q^{17} + 24 q^{21} - 20 q^{25} + 12 q^{33} + 12 q^{41} - 72 q^{49} + 24 q^{53} + 8 q^{57} + 4 q^{73} - 32 q^{77} + 36 q^{81} + 8 q^{85} + 48 q^{89} - 40 q^{93} - 12 q^{97}+O(q^{100}) \) Copy content Toggle raw display
