$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 2 q - 2 q^{2} + 2 q^{4} + 3 q^{5} + 2 q^{7} - 2 q^{8} - 3 q^{10} + 6 q^{11} + 3 q^{13} - 2 q^{14} + 2 q^{16} - q^{17} + 3 q^{20} - 6 q^{22} + 2 q^{23} - 3 q^{25} - 3 q^{26} + 2 q^{28} + 15 q^{29} + 4 q^{31}+ \cdots - 2 q^{98}+O(q^{100}) \) Copy content Toggle raw display
