$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 64 q - 36 q^{4} - 616 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 64 q - 36 q^{4} - 616 q^{9} - 104 q^{14} - 316 q^{16} + 256 q^{21} + 664 q^{25} + 1272 q^{29} - 740 q^{30} - 476 q^{36} + 352 q^{44} - 712 q^{46} + 1400 q^{49} + 492 q^{50} + 404 q^{56} + 348 q^{60} - 3204 q^{64} - 272 q^{65} - 1724 q^{70} - 1368 q^{74} - 336 q^{81} + 336 q^{84} + 1320 q^{85} + 10896 q^{86}+O(q^{100}) \) Copy content Toggle raw display
