Decomposition of \(S_{8}^{\mathrm{new}}(\Gamma_1(177))\)

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
177.8.a \(\chi_{177}(1, \cdot)\) 177.8.a.a 16 1
177.8.a.b 17
177.8.a.c 17

177.8.f \(\chi_{177}(2, \cdot)\) n/a 3864 28

"n/a" means that newforms for that character have not been added to the database yet
