Dimensions
The following table gives the dimensions of various subspaces of \(M_{8}(\Gamma_1(117))\).
| Total | New | Old | |
|---|---|---|---|
| Modular forms | 3624 | 2807 | 817 |

| Eisenstein series | 192 | 98 | 94 |
Trace form
Decomposition of \(S_{8}^{\mathrm{new}}(\Gamma_1(117))\)
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.
