$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 26 q + 4 q^{2} + 6 q^{3} + 36 q^{4} + 26 q^{5} - 4 q^{6} + 12 q^{8} + 44 q^{9} + 4 q^{10} + 14 q^{11} + 20 q^{12} + 14 q^{13} + 6 q^{15} + 64 q^{16} + 18 q^{17} + 8 q^{18} - 26 q^{19} + 36 q^{20} + 36 q^{22}+ \cdots + 24 q^{99}+O(q^{100}) \) Copy content Toggle raw display
