$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 3 q + 3 q^{2} - q^{3} + 3 q^{4} + 3 q^{5} - q^{6} - 2 q^{7} + 3 q^{8} + 4 q^{9} + 3 q^{10} - q^{12} + 3 q^{13} - 2 q^{14} - q^{15} + 3 q^{16} - 7 q^{17} + 4 q^{18} + 5 q^{19} + 3 q^{20} - q^{21} - 6 q^{23}+ \cdots - 11 q^{98}+O(q^{100}) \) Copy content Toggle raw display
