$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 2 q + 2 q^{5} - 2 q^{7} + 4 q^{11} + 2 q^{13} - 10 q^{17} + 4 q^{19} + 8 q^{23} + 8 q^{25} - 4 q^{29} - 12 q^{31} + 6 q^{35} - 6 q^{37} - 16 q^{41} - 10 q^{43} - 2 q^{47} - 8 q^{49} + 16 q^{53} - 12 q^{55}+ \cdots + 28 q^{97}+O(q^{100}) \) Copy content Toggle raw display
