$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 42 q + 5 q^{3} + 4 q^{5} - q^{7} - 2 q^{9} + 2 q^{11} + 14 q^{13} - q^{15} + 2 q^{17} - 26 q^{19} - 9 q^{21} - 10 q^{23} - 17 q^{25} + 11 q^{27} + 21 q^{29} - 32 q^{31} + 14 q^{33} + 25 q^{35} + 6 q^{37}+ \cdots + 94 q^{99}+O(q^{100}) \) Copy content Toggle raw display
