$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 40 q + 5 q^{2} - q^{4} + 8 q^{6} + 5 q^{8} + 10 q^{9} - 20 q^{10} - 6 q^{12} + 2 q^{14} + 22 q^{15} - 25 q^{16} + 4 q^{17} + 25 q^{18} + 8 q^{20} - 8 q^{23} - 40 q^{24} + 6 q^{25} - 20 q^{26} - 18 q^{28}+ \cdots - 144 q^{98}+O(q^{100}) \) Copy content Toggle raw display
