Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(17))\)

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
17.2.a \(\chi_{17}(1, \cdot)\) 17.2.a.a 1 1
17.2.b \(\chi_{17}(16, \cdot)\) None 0 1
17.2.c \(\chi_{17}(4, \cdot)\) None 0 2
