$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 28 q + 14 q^{3} - 28 q^{4} - 8 q^{7} - 14 q^{9} + 4 q^{10} - 14 q^{12} - 2 q^{13} - 4 q^{14} + 6 q^{15} + 28 q^{16} - 6 q^{17} + 2 q^{21} - 12 q^{22} - 12 q^{23} - 28 q^{25} + 24 q^{26} - 28 q^{27} + 8 q^{28}+ \cdots + 32 q^{98}+O(q^{100}) \) Copy content Toggle raw display
