$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 180 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 180 q - 12 q^{15} + 12 q^{25} + 24 q^{35} - 18 q^{41} + 18 q^{45} + 90 q^{49} + 36 q^{51} - 36 q^{55} - 12 q^{59} + 48 q^{69} - 24 q^{71} - 156 q^{79} + 24 q^{81} + 12 q^{85} - 36 q^{89} + 36 q^{91} + 78 q^{95} + 42 q^{99}+O(q^{100}) \) Copy content Toggle raw display
