$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q - 32 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 32 q - 32 q^{9} + 4 q^{23} + 48 q^{25} - 52 q^{29} - 64 q^{35} + 16 q^{39} - 8 q^{49} - 36 q^{71} - 8 q^{77} + 32 q^{81} - 28 q^{85} + 8 q^{93} - 28 q^{95}+O(q^{100}) \) Copy content Toggle raw display
