$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 4 q + 12 q^{11} - 8 q^{15} + 4 q^{23} - 8 q^{25} - 4 q^{37} + 16 q^{39} - 16 q^{43} + 12 q^{51} - 36 q^{53} - 28 q^{57} - 24 q^{65} - 4 q^{67} + 4 q^{71} - 16 q^{81} - 8 q^{85} - 24 q^{93} + 12 q^{95} + 20 q^{99}+O(q^{100}) \) Copy content Toggle raw display
