Trace form

\( 2 q - q^{3} - q^{4} - 2 q^{7} - q^{9} + O(q^{10}) \) \( 2 q - q^{3} - q^{4} - 2 q^{7} - q^{9} + 2 q^{12} + q^{13} - q^{16} + 2 q^{19} + q^{21} - q^{25} + 2 q^{27} + q^{28} - 2 q^{31} - q^{36} - 2 q^{37} - 2 q^{39} + q^{43} - q^{48} + q^{52} - q^{57} + q^{61} + q^{63} + 2 q^{64} + q^{67} + q^{73} + 2 q^{75} - q^{76} + q^{79} - q^{81} - 2 q^{84} - q^{91} + q^{93} - 2 q^{97} + O(q^{100}) \)

Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(57))\)

We only show spaces with odd parity, since no modular forms exist when this condition is not satisfied. Within each space \( S_k^{\mathrm{new}}(N, \chi) \) we list available newforms together with their dimension.
