$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 3 q - 3 q^{3} + 4 q^{5} - 3 q^{7} + 3 q^{9} - 4 q^{11} - 4 q^{15} + 4 q^{17} + 4 q^{19} + 3 q^{21} - 6 q^{23} + 9 q^{25} - 3 q^{27} + 6 q^{29} - 8 q^{31} + 4 q^{33} - 4 q^{35} + 4 q^{37} + 8 q^{41} - 8 q^{43}+ \cdots - 4 q^{99}+O(q^{100}) \) Copy content Toggle raw display
