$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 4 q + q^{2} + 3 q^{4} - 4 q^{5} - 11 q^{7} + 6 q^{8} - q^{10} + 2 q^{13} - 11 q^{14} - 3 q^{16} + 7 q^{17} - 3 q^{20} - q^{22} + 11 q^{23} + 4 q^{25} - 9 q^{26} - 13 q^{28} - 15 q^{29} + q^{31} + 3 q^{32}+ \cdots + 48 q^{98}+O(q^{100}) \) Copy content Toggle raw display
