$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 24 q - 96 q^{4} - 152 q^{9} + 36 q^{11} - 32 q^{14} - 248 q^{15} + 384 q^{16} + 184 q^{22} - 392 q^{23} - 56 q^{25} + 608 q^{36} + 720 q^{37} + 576 q^{42} - 144 q^{44} - 1472 q^{49} - 2744 q^{53} + 128 q^{56}+ \cdots + 4220 q^{99}+O(q^{100}) \) Copy content Toggle raw display
