## Hecke kernels

This newform subspace can be constructed as the intersection of the kernels of the following linear operators acting on $$S_{2}^{\mathrm{new}}(847, [\chi])$$:

 $$T_{2}^{4} + 5T_{2}^{3} + 15T_{2}^{2} + 25T_{2} + 25$$ T2^4 + 5*T2^3 + 15*T2^2 + 25*T2 + 25 $$T_{3}^{4} - 4T_{3}^{3} + 16T_{3}^{2} - 24T_{3} + 16$$ T3^4 - 4*T3^3 + 16*T3^2 - 24*T3 + 16 $$T_{13}^{4} + 4T_{13}^{3} + 16T_{13}^{2} + 24T_{13} + 16$$ T13^4 + 4*T13^3 + 16*T13^2 + 24*T13 + 16
