Decomposition of \(S_{12}^{\mathrm{new}}(\Gamma_1(7))\)

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
7.12.a \(\chi_{7}(1, \cdot)\) 7.12.a.a 2 1
7.12.a.b 3
7.12.c \(\chi_{7}(2, \cdot)\) 7.12.c.a 12 2
