$q$-expansion

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

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