$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 10 q - 2 q^{2} + 14 q^{4} - 6 q^{8} + 16 q^{9} + 2 q^{11} - 8 q^{15} + 14 q^{16} - 30 q^{18} + 14 q^{22} - 12 q^{23} - 20 q^{29} + 16 q^{30} + 16 q^{32} + 56 q^{36} - 2 q^{37} - 26 q^{39} - 4 q^{43} - 48 q^{44}+ \cdots - 56 q^{99}+O(q^{100}) \) Copy content Toggle raw display
