$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 60 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 60 q - 6 q^{11} + 33 q^{15} + 24 q^{19} - 24 q^{21} - 6 q^{25} + 12 q^{29} - 21 q^{35} - 24 q^{39} - 6 q^{41} - 42 q^{45} + 60 q^{49} + 36 q^{51} - 45 q^{55} + 60 q^{61} - 15 q^{65} - 48 q^{69} + 36 q^{71} - 60 q^{79} - 96 q^{81} + 18 q^{85} - 48 q^{89} - 48 q^{91} - 21 q^{95} - 162 q^{99}+O(q^{100}) \) Copy content Toggle raw display
