$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 256 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 256 q + 32 q^{14} - 8 q^{16} + 8 q^{18} - 8 q^{22} + 16 q^{23} + 40 q^{28} - 48 q^{35} + 16 q^{43} - 8 q^{44} - 48 q^{50} - 32 q^{53} + 64 q^{58} + 48 q^{60} - 144 q^{64} + 16 q^{67} + 72 q^{70} - 128 q^{71} + 232 q^{74} - 48 q^{78} + 176 q^{88} + 48 q^{91} - 152 q^{92} - 32 q^{98}+O(q^{100}) \) Copy content Toggle raw display
