Trace form
Decomposition of \(S_{6}^{\mathrm{new}}(\Gamma_1(961))\)
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
