Decomposition of \(S_{8}^{\mathrm{new}}(\Gamma_1(11))\)

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

11.8.a.b 4
11.8.c \(\chi_{11}(3, \cdot)\) 11.8.c.a 24 4
