$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 56 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 56 q + 80 q^{13} + 1784 q^{25} + 792 q^{49} + 2480 q^{61}+O(q^{100}) \) Copy content Toggle raw display
