$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q + 96 q^{2} + 40 q^{3} - 768 q^{4} - 136 q^{5} + 640 q^{6} + 536 q^{7} - 12288 q^{8} - 12014 q^{9} - 2176 q^{10} - 3448 q^{11} + 2560 q^{12} + 186 q^{13} + 8576 q^{14} + 10628 q^{15} - 49152 q^{16}+ \cdots + 16388620 q^{99}+O(q^{100}) \) Copy content Toggle raw display
