The following table gives the dimensions of various subspaces of \(M_{10}(\Gamma_1(128))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 4688 | 2616 | 2072 |

Trace form
Decomposition of \(S_{10}^{\mathrm{new}}(\Gamma_1(128))\)
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.
