Dimensions
The following table gives the dimensions of various subspaces of \(M_{7}(\Gamma_1(32))\).
Total | New | Old | |

Eisenstein series | 32 | 10 | 22 |
Trace form
Decomposition of \(S_{7}^{\mathrm{new}}(\Gamma_1(32))\)
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.
Decomposition of \(S_{7}^{\mathrm{old}}(\Gamma_1(32))\) into lower level spaces
\( S_{7}^{\mathrm{old}}(\Gamma_1(32)) \cong \) \(S_{7}^{\mathrm{new}}(\Gamma_1(4))\)\(^{\oplus 4}\)\(\oplus\)\(S_{7}^{\mathrm{new}}(\Gamma_1(8))\)\(^{\oplus 3}\)\(\oplus\)\(S_{7}^{\mathrm{new}}(\Gamma_1(16))\)\(^{\oplus 2}\)
