$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 40 q + 4 q^{3} + 8 q^{5} + 12 q^{6} + 20 q^{10} - 12 q^{12} - 8 q^{15} - 64 q^{16} - 16 q^{17} + 24 q^{18} - 8 q^{19} - 20 q^{20} - 8 q^{23} - 12 q^{24} - 8 q^{27} + 8 q^{29} + 36 q^{31} + 72 q^{33} - 8 q^{34}+ \cdots - 16 q^{99}+O(q^{100}) \) Copy content Toggle raw display
