Hi!
I've been working on some projects recently where the majority of my work is python, but I'm calling to SageMath to get the polynomial rings of finite fields, which currently uses the NTL bindi…

I expected the following to work, treating 𝔽₈ as an 𝔽₂ vector space:
```

(Univariate Polynomial Ring in X over Integers modulo 2, X)

Deep-copying matrices over laurent-series-rings whose base-rings are GF(pn) with large enough values of p,n, seem to fail for most matrices.

There should be a proper class for Selmer groups of number fields K(S,m), similar to the existing and related S-unit groups and S-class-group classes: it fits into the short exact sequence
