Dimensions
The following table gives the dimensions of various subspaces of \(M_{1}(\Gamma_1(68))\).
| Total | New | Old | |
|---|---|---|---|
| Modular forms | 43 | 17 | 26 |
| Cusp forms | 3 | 3 | 0 |
| Eisenstein series | 40 | 14 | 26 |
The following table gives the dimensions of subspaces with specified projective image type.

Trace form
Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(68))\)
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.
