$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 3 q + q^{3} - q^{7} + 4 q^{9} - q^{11} + 14 q^{13} - 4 q^{17} - 7 q^{19} - 13 q^{21} - 7 q^{23} + q^{27} - 18 q^{29} - 5 q^{31} + 20 q^{33} + 8 q^{37} - 3 q^{39} - 4 q^{41} + 12 q^{43} - 3 q^{47} - 8 q^{49}+ \cdots + 15 q^{99}+O(q^{100}) \) Copy content Toggle raw display
