Dimensions
The following table gives the dimensions of various subspaces of \(M_{1}(\Gamma_1(148))\).

Trace form
Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(148))\)
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.
