Decomposition of \(S_{3}^{\mathrm{new}}(\Gamma_1(14))\)

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
14.3.b \(\chi_{14}(13, \cdot)\) None 0 1
14.3.d \(\chi_{14}(3, \cdot)\) 14.3.d.a 4 2

Decomposition of \(S_{3}^{\mathrm{old}}(\Gamma_1(14))\) into lower level spaces
