$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 88 q + 176 q^{4} - 40 q^{10} + 352 q^{16} + 32 q^{19} - 48 q^{25} - 64 q^{31} - 80 q^{34} - 80 q^{40} - 1128 q^{49} + 64 q^{55} - 656 q^{61} + 704 q^{64} - 224 q^{70} + 64 q^{76} - 32 q^{79} + 264 q^{85} + 800 q^{91} - 320 q^{94}+O(q^{100}) \) Copy content Toggle raw display
