$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 60 q + 3 q^{3} - 3 q^{9} + 3 q^{13} + 9 q^{15} + 6 q^{17} - 3 q^{19} + 6 q^{25} - 6 q^{27} - 6 q^{29} + 45 q^{33} + 24 q^{35} - 18 q^{39} - 3 q^{41} + 21 q^{43} - 45 q^{45} - 18 q^{47} - 30 q^{49} + 6 q^{51}+ \cdots + 3 q^{99}+O(q^{100}) \) Copy content Toggle raw display
