Dimensions
The following table gives the dimensions of various subspaces of \(M_{1}(\Gamma_1(100))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 74 | 25 | 49 |
Cusp forms | 4 | 4 | 0 |
Eisenstein series | 70 | 21 | 49 |
The following table gives the dimensions of subspaces with specified projective image type.
\(D_n\) | \(A_4\) | \(S_4\) | \(A_5\) | |

Dimension | 4 | 0 | 0 | 0 |
Trace form
Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(100))\)
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.
