The following table gives the dimensions of various subspaces of \(M_{6}(\Gamma_1(387))\).
Total | New | Old | |
---|---|---|---|
Modular forms | 28056 | 22106 | 5950 |
Cusp forms | 27384 | 21738 | 5646 |

Trace form
Decomposition of \(S_{6}^{\mathrm{new}}(\Gamma_1(387))\)
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.
"n/a" means that newforms for that character have not been added to the database yet
Decomposition of \(S_{6}^{\mathrm{old}}(\Gamma_1(387))\) into lower level spaces
\( S_{6}^{\mathrm{old}}(\Gamma_1(387)) \cong \) \(S_{6}^{\mathrm{new}}(\Gamma_1(3))\)\(^{\oplus 4}\)\(\oplus\)\(S_{6}^{\mathrm{new}}(\Gamma_1(9))\)\(^{\oplus 2}\)\(\oplus\)\(S_{6}^{\mathrm{new}}(\Gamma_1(43))\)\(^{\oplus 3}\)\(\oplus\)\(S_{6}^{\mathrm{new}}(\Gamma_1(129))\)\(^{\oplus 2}\)
