Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(93))\)
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 the newforms together with their dimension.
Label | \(\chi\) | Newforms | Dimension | \(\chi\) degree |

93.1.b | \(\chi_{93}(32, \cdot)\) | None | 0 | 1 |
93.1.d | \(\chi_{93}(61, \cdot)\) | None | 0 | 1 |
93.1.h | \(\chi_{93}(5, \cdot)\) | None | 0 | 2 |
93.1.i | \(\chi_{93}(37, \cdot)\) | None | 0 | 2 |
93.1.j | \(\chi_{93}(46, \cdot)\) | None | 0 | 4 |
93.1.l | \(\chi_{93}(2, \cdot)\) | 93.1.l.a | 4 | 4 |
93.1.n | \(\chi_{93}(13, \cdot)\) | None | 0 | 8 |
