Decomposition of \(S_{3}^{\mathrm{new}}(\Gamma_1(30))\)

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.

Label \(\chi\) Newforms Dimension \(\chi\) degree
30.3.b \(\chi_{30}(29, \cdot)\) 30.3.b.a 4 1
30.3.d \(\chi_{30}(11, \cdot)\) 30.3.d.a 4 1
