$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 3 q - 3 q^{2} + 3 q^{4} - 3 q^{5} - 5 q^{7} - 3 q^{8} + 3 q^{10} - 3 q^{11} - 2 q^{13} + 5 q^{14} + 3 q^{16} + 8 q^{17} - 6 q^{19} - 3 q^{20} + 3 q^{22} + 3 q^{25} + 2 q^{26} - 5 q^{28} - 10 q^{29} - 3 q^{31}+ \cdots + 2 q^{98}+O(q^{100}) \) Copy content Toggle raw display
