$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 30 q - 6 q^{2} - 9 q^{3} - 12 q^{4} - 20 q^{5} - 18 q^{6} - 10 q^{7} - 24 q^{8} - 27 q^{9} + 4 q^{10} + 35 q^{11} - 36 q^{12} + 13 q^{13} - 64 q^{14} + 72 q^{15} - 48 q^{16} + 45 q^{17} - 54 q^{18} - 7 q^{19}+ \cdots - 675 q^{99}+O(q^{100}) \) Copy content Toggle raw display
