$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 8 q - 8 q^{2} + 8 q^{4} - 5 q^{5} - 8 q^{7} - 8 q^{8} + 5 q^{10} + q^{13} + 8 q^{14} + 8 q^{16} + 13 q^{17} + q^{19} - 5 q^{20} + 14 q^{23} + q^{25} - q^{26} - 8 q^{28} + 18 q^{29} - 3 q^{31} - 8 q^{32}+ \cdots - 8 q^{98}+O(q^{100}) \) Copy content Toggle raw display
