Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(2012))\)

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 available newforms together with their dimension.

Label \(\chi\) Newforms Dimension \(\chi\) degree
2012.2.a \(\chi_{2012}(1, \cdot)\) 2012.2.a.a 21 1
2012.2.a.b 21
2012.2.b \(\chi_{2012}(2011, \cdot)\) n/a 250 1
2012.2.e \(\chi_{2012}(9, \cdot)\) n/a 10500 250
2012.2.h \(\chi_{2012}(15, \cdot)\) n/a 62500 250

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