The following table gives the dimensions of various subspaces of \(M_{5}(\Gamma_1(768))\).

Trace form
Decomposition of \(S_{5}^{\mathrm{new}}(\Gamma_1(768))\)
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 available newforms together with their dimension.
