$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 160 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 160 q - 8 q^{16} - 8 q^{19} - 8 q^{24} + 40 q^{26} - 40 q^{28} - 48 q^{35} - 8 q^{36} + 48 q^{38} + 56 q^{44} + 160 q^{49} - 8 q^{54} - 56 q^{58} - 32 q^{61} + 24 q^{62} + 72 q^{64} + 48 q^{66} - 40 q^{68} + 40 q^{74} + 32 q^{76} + 56 q^{80} - 160 q^{81} - 120 q^{82} - 80 q^{83} + 32 q^{85} - 24 q^{92} - 40 q^{96}+O(q^{100}) \) Copy content Toggle raw display
