$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 32 q - 8 q^{5} + 32 q^{9} + 8 q^{17} + 8 q^{21} - 16 q^{25} + 16 q^{29} + 56 q^{33} - 48 q^{45} + 112 q^{53} + 8 q^{57} - 8 q^{61} - 72 q^{65} - 40 q^{69} - 8 q^{73} + 144 q^{77} - 64 q^{81} + 40 q^{85}+ \cdots + 72 q^{97}+O(q^{100}) \) Copy content Toggle raw display
