$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 4 q - q^{3} - 4 q^{5} - 3 q^{7} + 9 q^{9} - 5 q^{11} + q^{15} - 5 q^{17} - 4 q^{19} - 4 q^{21} + 4 q^{25} + 14 q^{27} - 5 q^{29} + 13 q^{31} + 11 q^{33} + 3 q^{35} + 3 q^{37} + 6 q^{39} - 20 q^{41} - 12 q^{43}+ \cdots + 39 q^{97}+O(q^{100}) \) Copy content Toggle raw display
