$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q + 4 q^{7} + 4 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 32 q + 4 q^{7} + 4 q^{9} - 16 q^{15} + 6 q^{21} + 68 q^{25} - 68 q^{37} - 32 q^{39} + 120 q^{43} - 64 q^{49} + 56 q^{51} - 44 q^{57} + 42 q^{63} + 4 q^{67} - 56 q^{79} - 28 q^{81} - 44 q^{91} - 28 q^{93}+O(q^{100}) \) Copy content Toggle raw display
