$q$-expansion

The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.

\(\operatorname{Tr}(f)(q) = \) \( 24 q+O(q^{10}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q) = \) \( 24 q + 16 q^{19} - 8 q^{25} + 88 q^{49} + 64 q^{55} - 48 q^{61}+O(q^{100}) \) Copy content Toggle raw display

Hecke kernels

This newform subspace can be constructed as the kernel of the linear operator \( T_{7}^{6} + 10T_{7}^{4} + 26T_{7}^{2} + 6 \) acting on \(S_{2}^{\mathrm{new}}(3420, [\chi])\). Copy content Toggle raw display
