$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 72 q + 12 q^{5} - 20 q^{7} + 8 q^{11} + 24 q^{13} - 16 q^{17} + 20 q^{21} - 28 q^{23} + 48 q^{29} - 28 q^{31} + 24 q^{33} + 68 q^{35} + 20 q^{37} + 32 q^{41} - 12 q^{45} + 44 q^{47} - 4 q^{51} + 48 q^{55}+ \cdots - 16 q^{99}+O(q^{100}) \) Copy content Toggle raw display
