Trace form

\( 26q + O(q^{10}) \) \( 26q + 4q^{11} + 4q^{16} - 18q^{36} - 4q^{46} - 8q^{71} - 4q^{81} - 4q^{86} + O(q^{100}) \)

Decomposition of \(S_{1}^{\mathrm{new}}(\Gamma_1(1225))\)

We only show spaces with odd 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.
