$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 6 q^{5} + 44 q^{9}+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q - 6 q^{5} + 44 q^{9} + 8 q^{19} - 166 q^{25} - 24 q^{31} + 54 q^{35} - 280 q^{39} - 248 q^{41} - 190 q^{45} - 644 q^{49} - 100 q^{51} + 152 q^{59} - 288 q^{69} - 352 q^{71} - 368 q^{81} + 102 q^{95}+O(q^{100}) \) Copy content Toggle raw display
