$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q + 4 q^{2} + 28 q^{4} - 24 q^{5} + 12 q^{8} - 4 q^{10} + 16 q^{11} + 24 q^{13} + 32 q^{16} + 8 q^{17} - 24 q^{19} - 28 q^{20} + 40 q^{23} + 24 q^{25} + 4 q^{26} + 16 q^{29} - 16 q^{31} + 28 q^{32} - 24 q^{34}+ \cdots - 24 q^{97}+O(q^{100}) \) Copy content Toggle raw display
