$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 7 q - 5 q^{3} + 2 q^{5} + 4 q^{9} - 4 q^{11} + 10 q^{13} - q^{15} + 6 q^{17} - 9 q^{19} - 7 q^{23} + 11 q^{25} - 8 q^{27} + 7 q^{29} - 8 q^{31} - 7 q^{33} - 9 q^{37} - 8 q^{39} + 9 q^{41} - 9 q^{43} + 8 q^{45}+ \cdots + 2 q^{99}+O(q^{100}) \) Copy content Toggle raw display
