$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 48 q - 40 q^{4} + 8 q^{14} + 64 q^{16} + 12 q^{19} - 52 q^{24} - 16 q^{26} + 20 q^{31} + 32 q^{39} - 24 q^{46} - 36 q^{51} - 116 q^{54} - 28 q^{56} + 28 q^{59} - 20 q^{61} - 24 q^{64} - 76 q^{66} + 68 q^{69}+ \cdots - 48 q^{99}+O(q^{100}) \) Copy content Toggle raw display
