Decomposition of \(S_{4}^{\mathrm{new}}(\Gamma_1(46))\)

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.

Label \(\chi\) Newforms Dimension \(\chi\) degree
46.4.a \(\chi_{46}(1, \cdot)\) 46.4.a.a 1 1
46.4.a.b 1
46.4.a.c 2
