$q$-expansion

The algebraic \(q\)-expansion of this newform has not been computed, but we have computed the trace expansion.

\(\operatorname{Tr}(f)(q) = \) \( 24 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q - 408 q^{19} - 3000 q^{25} + 2208 q^{31} - 2952 q^{43} + 12168 q^{49} + 2544 q^{55} - 5568 q^{61} + 5208 q^{67} + 5112 q^{73} - 6960 q^{79} - 14784 q^{85} - 14208 q^{91} + 8040 q^{97}+O(q^{100}) \) Copy content Toggle raw display
