$q$-expansion

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

\(\operatorname{Tr}(f)(q) = \) \( 28 q - 52 q^{3} - 928 q^{6} - 1348 q^{7} - 416 q^{10} + 3328 q^{12} - 21840 q^{13} - 37672 q^{15} - 114688 q^{16} + 50624 q^{18} - 142744 q^{21} - 47008 q^{22} + 419744 q^{25} + 212972 q^{27} - 86272 q^{28}+ \cdots + 82948404 q^{97}+O(q^{100}) \) Copy content Toggle raw display
