$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 3 q - q^{3} - 3 q^{5} + 5 q^{7} + 12 q^{9} - 6 q^{11} - 7 q^{13} + q^{15} + 7 q^{17} + 4 q^{19} - 12 q^{21} + 3 q^{25} - q^{27} + 10 q^{29} + 8 q^{31} + 2 q^{33} - 5 q^{35} - 3 q^{37} + 23 q^{39} + 14 q^{41}+ \cdots - 24 q^{99}+O(q^{100}) \) Copy content Toggle raw display
