$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 56 q^{7} - 600 q^{25} - 264 q^{31} + 456 q^{49} - 880 q^{55} - 432 q^{73} + 1656 q^{79} + 1584 q^{97}+O(q^{100}) \) Copy content Toggle raw display
