$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q - 12 q^{10} + 32 q^{16} - 8 q^{22} + 4 q^{25} - 64 q^{28} - 24 q^{31} - 20 q^{37} - 132 q^{40} - 56 q^{43} + 40 q^{46} + 108 q^{52} + 68 q^{58} - 24 q^{61} + 24 q^{67} + 28 q^{70} + 36 q^{73} + 12 q^{82} + 152 q^{85} + 56 q^{88} - 72 q^{91}+O(q^{100}) \) Copy content Toggle raw display
