$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 96 q - 48 q^{3} - 48 q^{9} + 13 q^{10} + 14 q^{14} + 4 q^{16} - 22 q^{20} + 96 q^{27} + 4 q^{28} - 5 q^{30} + 30 q^{32} - 8 q^{35} + 12 q^{38} - 23 q^{40} + 2 q^{42} - 16 q^{44} - 22 q^{46} - 8 q^{48} + 12 q^{50}+ \cdots + 2 q^{98}+O(q^{100}) \) Copy content Toggle raw display
