Dimensions
The following table gives the dimensions of various subspaces of \(M_{24}(\Gamma_1(48))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 1500 | 625 | 875 |
Cusp forms | 1444 | 617 | 827 |
Eisenstein series | 56 | 8 | 48 |
Trace form
Decomposition of \(S_{24}^{\mathrm{new}}(\Gamma_1(48))\)
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.
Label | \(\chi\) | Newforms | Dimension | \(\chi\) degree |

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