Trace form

\( q - q^{4} - q^{7} + O(q^{10}) \) \( q - q^{4} - q^{7} + q^{16} + q^{25} + q^{28} - 2q^{37} - 2q^{43} + q^{49} - q^{64} + 2q^{67} + 2q^{79} + O(q^{100}) \)

Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(63))\)

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 the newforms together with their dimension.
