Dimensions
The following table gives the dimensions of various subspaces of \(M_{6}(\Gamma_1(7))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 13 | 11 | 2 |
Cusp forms | 7 | 7 | 0 |
Eisenstein series | 6 | 4 | 2 |
Trace form
Decomposition of \(S_{6}^{\mathrm{new}}(\Gamma_1(7))\)
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 |

7.6.a | \(\chi_{7}(1, \cdot)\) | 7.6.a.a | 1 | 1 |
7.6.a.b | 2 | |||
7.6.c | \(\chi_{7}(2, \cdot)\) | 7.6.c.a | 4 | 2 |
