Dimensions
The following table gives the dimensions of various subspaces of \(M_{6}(\Gamma_1(257))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 13888 | 13886 | 2 |
Cusp forms | 13632 | 13632 | 0 |
Eisenstein series | 256 | 254 | 2 |
Trace form
Decomposition of \(S_{6}^{\mathrm{new}}(\Gamma_1(257))\)
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 |

257.6.a.b | 57 | |||
257.6.b | \(\chi_{257}(256, \cdot)\) | n/a | 106 | 1 |
257.6.c | \(\chi_{257}(16, \cdot)\) | n/a | 212 | 2 |
257.6.d | \(\chi_{257}(4, \cdot)\) | n/a | 424 | 4 |
257.6.e | \(\chi_{257}(2, \cdot)\) | n/a | 848 | 8 |
