$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 68 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 68 q + 8 q^{15} + 32 q^{21} - 4 q^{23} + 12 q^{25} - 12 q^{33} + 12 q^{35} + 24 q^{37} - 24 q^{47} - 48 q^{55} + 72 q^{65} + 14 q^{67} - 8 q^{71} + 32 q^{73} - 52 q^{77} - 140 q^{81} - 40 q^{83} + 16 q^{91} + 24 q^{93}+O(q^{100}) \) Copy content Toggle raw display
