$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 52 q + 7 q^{3} - 194 q^{4} - 6 q^{6} - 39 q^{7} - 213 q^{9} - 23 q^{10} - 45 q^{11} - 112 q^{12} - 90 q^{13} - 116 q^{14} - 27 q^{15} + 598 q^{16} + 274 q^{17} + 321 q^{18} + 9 q^{19} - 138 q^{20} - 3 q^{21}+ \cdots + 2220 q^{98}+O(q^{100}) \) Copy content Toggle raw display
