Dimensions

The following table gives the dimensions of various subspaces of \(M_{2}(\Gamma_1(8400))\).

Total New Old
Modular forms 1862016 688672 1173344
Cusp forms 1824385 684980 1139405
Eisenstein series 37631 3692 33939

Decomposition of \(S_{2}^{\mathrm{new}}(\Gamma_1(8400))\)

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.
