Comment (by vdelecroix):
Replying to [comment:14 ncohen]:
> Hello,
>
> I tried to simplify the explanations a bit but I still do not understand
the implementation. In particular I do not understand why you have this
`-1` in the definition of `A`, and why you seem to solve a tiling problem
on `A` and not on `\Delta A`.
`A` appears explicitly when you compute `\Delta {1,r,r^2,...,r^(k-1)\}`.
Its definition is obtained from differences already.
> Also, what would you think of removing the `one_cyclic_tiling` function?
The name is not particularly meaningful, it is three lines long, only used
once?...
True. But I wonder if we can do better for that particular problem. I also
thought about moving it in some tiling stuff in `sage.combinat`. That way
it would be better advertised.
> Could you also add your new functions to the index at the top of the
file?
Right
> My modifications can be found at `u/ncohen/16866`, but of course in that
version your comments in the code use notations that I removed from the
function's doc.
I am having a look right now.
