$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 4 q + 4 q^{2} + 4 q^{4} - 4 q^{5} - 6 q^{7} + 4 q^{8} - 4 q^{10} - 4 q^{13} - 6 q^{14} + 4 q^{16} - 4 q^{17} - 4 q^{20} - 10 q^{23} + 4 q^{25} - 4 q^{26} - 6 q^{28} - 8 q^{29} + 8 q^{31} + 4 q^{32} - 4 q^{34}+ \cdots - 4 q^{98}+O(q^{100}) \) Copy content Toggle raw display
