Dimensions
The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(68))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 184 | 100 | 84 |
Cusp forms | 105 | 68 | 37 |
Eisenstein series | 79 | 32 | 47 |
Trace form
Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(68))\)
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.
Decomposition of \(S_{2}^{\mathrm{old}}(\Gamma_1(68))\) into lower level spaces
\( S_{2}^{\mathrm{old}}(\Gamma_1(68)) \cong \) \(S_{2}^{\mathrm{new}}(\Gamma_1(17))\)\(^{\oplus 3}\)\(\oplus\)\(S_{2}^{\mathrm{new}}(\Gamma_1(34))\)\(^{\oplus 2}\)
