$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 40 q + 8 q^{7} + 12 q^{13} + 28 q^{19} + 36 q^{31} - 40 q^{37} - 72 q^{43} - 36 q^{49} - 32 q^{61} + 16 q^{67} + 28 q^{73} + 48 q^{79} - 20 q^{85} + 132 q^{91} + 48 q^{97}+O(q^{100}) \) Copy content Toggle raw display
