Decomposition of \(S_{3}^{\mathrm{new}}(\Gamma_1(138))\)

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 available newforms together with their dimension.

Label \(\chi\) Newforms Dimension \(\chi\) degree

138.3.c \(\chi_{138}(47, \cdot)\) 138.3.c.a 16 1
