$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 4 q + q^{2} - 4 q^{3} + 5 q^{4} + 4 q^{5} - q^{6} - 2 q^{7} - 6 q^{8} + 4 q^{9} + q^{10} + 4 q^{11} - 5 q^{12} - 4 q^{14} - 4 q^{15} + 3 q^{16} + q^{18} - 4 q^{19} + 5 q^{20} + 2 q^{21} + q^{22} + 6 q^{24}+ \cdots + 4 q^{99}+O(q^{100}) \) Copy content Toggle raw display
