$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 22q - 66q^{9} + O(q^{10}) \)
\(\operatorname{Tr}(f)(q) = \) \( 22q - 66q^{9} + 110q^{25} - 11q^{42} - 33q^{44} + 55q^{48} - 154q^{49} + 77q^{54} - 99q^{62} - 121q^{72} + 198q^{81} + 143q^{84} + 165q^{98} + O(q^{100}) \)
