$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 25 q + 11 q^{2} + 25 q^{3} + 31 q^{4} - 25 q^{5} + 11 q^{6} - 7 q^{7} + 33 q^{8} + 25 q^{9}+O(q^{10}) \) Copy content Toggle raw display
