$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 2 q - 2 q^{9} + 8 q^{11} - 8 q^{15} + 2 q^{23} + 6 q^{25} - 12 q^{29} + 4 q^{37} - 12 q^{39} + 12 q^{53} - 24 q^{57} + 24 q^{65} - 8 q^{67} + 16 q^{71} + 8 q^{79} - 10 q^{81} + 4 q^{93} + 48 q^{95} - 8 q^{99}+O(q^{100}) \) Copy content Toggle raw display
