The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(402))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 4752 | 1123 | 3629 |

Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(402))\)
We only show spaces with even 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.
