$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 2 q - 3 q^{2} + 3 q^{4} + 2 q^{5} - 4 q^{7} - 6 q^{8} - 3 q^{10} + 7 q^{11} + 10 q^{13} + q^{14} + 13 q^{16} + 12 q^{17} + 3 q^{20} - 13 q^{22} + q^{23} + 2 q^{25} - 15 q^{26} + 9 q^{28} - 3 q^{29} + 15 q^{31}+ \cdots + 14 q^{98}+O(q^{100}) \) Copy content Toggle raw display
