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

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

14.14.a.b 1

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