$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q + 12 q^{4} + 12 q^{5}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 32 q + 12 q^{4} + 12 q^{5} - 2 q^{11} + 32 q^{14} - 20 q^{16} + 8 q^{22} - 24 q^{23} + 24 q^{26} - 12 q^{31} - 32 q^{37} - 24 q^{38} + 28 q^{44} - 24 q^{47} - 36 q^{49} - 36 q^{53} + 56 q^{56} + 12 q^{58} + 48 q^{59} + 8 q^{64} + 20 q^{67} + 24 q^{70} - 72 q^{71} - 72 q^{80} - 48 q^{82} - 64 q^{86} + 24 q^{88} - 60 q^{89} - 28 q^{91} + 16 q^{92}+O(q^{100}) \) Copy content Toggle raw display
