$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 18 q - 6 q^{3} - 18 q^{5} + 24 q^{9} - 18 q^{11} - 18 q^{13} + 6 q^{15} + 15 q^{17} + q^{19} - 6 q^{21} + 18 q^{25} - 24 q^{27} - 8 q^{29} + 2 q^{31} + 6 q^{33} - 21 q^{37} + 6 q^{39} + 11 q^{41} - 9 q^{43}+ \cdots - 24 q^{99}+O(q^{100}) \) Copy content Toggle raw display
