The dimension is sufficiently large that we do not compute an algebraic \(q\)-expansion, but we have computed the trace expansion.
For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.

This newform does not admit any (nontrivial) inner twists.
This newform subspace can be constructed as the kernel of the linear operator
