Dimensions
The following table gives the dimensions of various subspaces of \(M_{8}(\Gamma_1(32))\).
Total | New | Old | |

Trace form
Decomposition of \(S_{8}^{\mathrm{new}}(\Gamma_1(32))\)
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 \(S_{8}^{\mathrm{old}}(\Gamma_1(32))\) into lower level spaces
\( S_{8}^{\mathrm{old}}(\Gamma_1(32)) \cong \) \(S_{8}^{\mathrm{new}}(\Gamma_1(2))\)\(^{\oplus 5}\)\(\oplus\)\(S_{8}^{\mathrm{new}}(\Gamma_1(8))\)\(^{\oplus 3}\)\(\oplus\)\(S_{8}^{\mathrm{new}}(\Gamma_1(16))\)\(^{\oplus 2}\)
