$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 288 q - 9 q^{3} - 6 q^{4} - 6 q^{7} - 3 q^{9} - 18 q^{10} - 27 q^{12} - 36 q^{13} - 15 q^{15} + 6 q^{16} - 18 q^{18} - 72 q^{19} + 12 q^{21} - 9 q^{24} + 18 q^{25} + 27 q^{27} - 108 q^{28} - 6 q^{30} - 9 q^{33}+ \cdots - 24 q^{99}+O(q^{100}) \) Copy content Toggle raw display
