$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 28 q - 129 q^{2} + 3345 q^{3} - 212993 q^{4} - 152655 q^{5} + 2208231 q^{6} + 803705 q^{7} + 20162658 q^{8} - 15596991 q^{9} + 65532 q^{10} - 60735990 q^{11} + 182013108 q^{12} - 41509093 q^{13} + 215313024 q^{14}+ \cdots + 54\!\cdots\!45 q^{99}+O(q^{100}) \) Copy content Toggle raw display
