$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 2 q - 2 q^{3} - q^{5} - 2 q^{7} + 2 q^{9} - q^{11} - 3 q^{13} + q^{15} - 2 q^{17} - 12 q^{19} + 2 q^{21} + 6 q^{23} + 11 q^{25} - 2 q^{27} + 2 q^{29} + q^{33} + q^{35} + 3 q^{37} + 3 q^{39} + 10 q^{41}+ \cdots - q^{99}+O(q^{100}) \) Copy content Toggle raw display
