$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q + 4 q^{2} - 4 q^{3} + 32 q^{4} + 8 q^{5} - 14 q^{6} + 6 q^{7} - 12 q^{8} - 6 q^{10} - 36 q^{12} + 20 q^{13} - 28 q^{14} + 6 q^{15} + 24 q^{16} + 4 q^{19} + 26 q^{20} + 20 q^{23} - 18 q^{24} - 40 q^{26}+ \cdots + 36 q^{99}+O(q^{100}) \) Copy content Toggle raw display
