Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(1664))\)
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.
Decomposition of \(S_{1}^{\mathrm{old}}(\Gamma_1(1664))\) into lower level spaces
