The following table gives the dimensions of various subspaces of \(M_{5}(\Gamma_1(144))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 2416 | 1046 | 1370 |

Decomposition of \(S_{5}^{\mathrm{new}}(\Gamma_1(144))\)
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 the newforms together with their dimension.
