$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 12 q^{2} + 8 q^{3} - 16 q^{5} + 8 q^{6} + 24 q^{7} - 48 q^{8} - 28 q^{9} + 16 q^{11} - 96 q^{14} + 116 q^{15} + 48 q^{16} + 56 q^{18} + 92 q^{19} - 16 q^{20} + 256 q^{21} + 32 q^{22} - 16 q^{24}+ \cdots - 224 q^{99}+O(q^{100}) \) Copy content Toggle raw display
