$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 30 q + 6 q^{2} - 9 q^{3} - 12 q^{4} - 4 q^{5} + 18 q^{6} + 4 q^{7} + 24 q^{8} - 27 q^{9} - 36 q^{10} - 5 q^{11} - 36 q^{12} - 59 q^{13} + 36 q^{14} + 120 q^{15} - 48 q^{16} - 291 q^{17} + 54 q^{18} + 319 q^{19}+ \cdots - 1827 q^{99}+O(q^{100}) \) Copy content Toggle raw display
