Decomposition of \(S_{13}^{\mathrm{new}}(\Gamma_1(14))\)

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
14.13.b \(\chi_{14}(13, \cdot)\) 14.13.b.a 8 1
14.13.d \(\chi_{14}(3, \cdot)\) 14.13.d.a 16 2

Decomposition of \(S_{13}^{\mathrm{old}}(\Gamma_1(14))\) into lower level spaces
