$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 2 q - 2 q^{3} + 4 q^{5} - 2 q^{7} + 6 q^{9} - 2 q^{13} - 4 q^{15} + 8 q^{17} - 4 q^{19} + 2 q^{21} + q^{23} - 2 q^{25} - 20 q^{27} - 5 q^{29} - 4 q^{35} + 13 q^{37} + 12 q^{39} - 10 q^{41} + 15 q^{43}+ \cdots - 4 q^{97}+O(q^{100}) \) Copy content Toggle raw display
