$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 48 q + 4 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 48 q + 4 q^{9} + 8 q^{15} + 4 q^{21} - 40 q^{25} + 40 q^{43} + 16 q^{49} - 12 q^{51} + 40 q^{67} - 36 q^{81} - 24 q^{85} - 24 q^{93}+O(q^{100}) \) Copy content Toggle raw display
