$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q + 3881794291104 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 32 q + 3881794291104 q^{9} - 39116014350400 q^{13} + 13\!\cdots\!68 q^{21}+ \cdots - 52\!\cdots\!00 q^{97}+O(q^{100}) \) Copy content Toggle raw display
