Dimensions
The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(4013))\).
| Total | New | Old | |
|---|---|---|---|
| Modular forms | 673013 | 673013 | 0 |
| Cusp forms | 669002 | 669002 | 0 |
| Eisenstein series | 4011 | 4011 | 0 |
Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(4013))\)
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.

| 4013.2.a.b | 157 | |||
| 4013.2.a.c | 176 | |||
| 4013.2.b | \(\chi_{4013}(4012, \cdot)\) | n/a | 334 | 1 |

"n/a" means that newforms for that character have not been added to the database yet
