$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 17 q - 2 q^{3} + 16 q^{4} - 7 q^{5} - 3 q^{6} - 8 q^{7} - 6 q^{8} + 17 q^{9} - 4 q^{10} + 17 q^{11} - 25 q^{12} - 3 q^{13} + 23 q^{14} + q^{15} + 10 q^{16} + 3 q^{17} + 19 q^{18} - 3 q^{19} - 13 q^{20}+ \cdots + 17 q^{99}+O(q^{100}) \) Copy content Toggle raw display
