Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(531))\)
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 |

531.1.b | \(\chi_{531}(296, \cdot)\) | None | 0 | 1 |
