The following error occurs when using `PreImage` on a subgroup that is not an element of the image:
```

Basically the opposite of #220. I've got a univariate polynomial over a multivariate polynomial ring, and I'd like to convert it into a multivariate polynomial ring with one more variable. How to do t…

Two decomposition is isomorphic if $P\ell_iP^\dagger$ and $Pm_iP^\dagger$. Can I rederive the magic basis?
Now that I have the kroncker sum representation of $\mathfrak{su}(2) \otimes \mathfrak{su}…

For permutations on finite sets, as we have in `Data.Fin.Permutation`, it's possible to define their [parity](https://en.wikipedia.org/wiki/Parity_of_a_permutation). This isn't hard to define with wha…

How I state later stuff depends on the implementation - I'm not asking for things to be implemented now, I just want to know how one intends to so that I can comply.
