$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q + 16 q^{9} - 8 q^{25} - 32 q^{29} - 16 q^{51} + 40 q^{65} + 128 q^{71} + 16 q^{79} - 16 q^{81} - 80 q^{85} + 48 q^{95}+O(q^{100}) \) Copy content Toggle raw display
