$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 3 q - 3 q^{3} - q^{5} - 3 q^{7} + 3 q^{9} - 2 q^{11} + 3 q^{13} + q^{15} + 2 q^{17} - 8 q^{19} + 3 q^{21} - 3 q^{23} - 3 q^{27} + 2 q^{29} - 10 q^{31} + 2 q^{33} + q^{35} - 12 q^{37} - 3 q^{39} + 16 q^{41}+ \cdots - 2 q^{99}+O(q^{100}) \) Copy content Toggle raw display
