$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 40 q + 8 q^{2} - 18 q^{3} - 34 q^{4} - 24 q^{5} + 30 q^{6} + 70 q^{7} - 72 q^{8} - 136 q^{9} + 216 q^{10} - 42 q^{11} + 288 q^{12} + 49 q^{14} - 108 q^{15} - 98 q^{16} - 268 q^{17} - 173 q^{18} - 369 q^{19}+ \cdots - 8829 q^{99}+O(q^{100}) \) Copy content Toggle raw display
