## 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 the newforms together with their dimension.

Label $$\chi$$ Newforms Dimension $$\chi$$ degree

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