comment Extending a partial order to antichains
Thanks for this remark! In my answer I was implicitly thinking about finite posets, even though the question was more general. I rephrased accordingly.

comment Undistinguishable elements in posets
@YannPequignot: You are entirely right, my "indistinguishable sets" are exactly this notion of interval, thanks a lot for pointing this out. Please post your comment as an answer and I will accept it. Thanks! :)

comment Small posets with prescribed number of linear extensions
@talegari: No I mean that their sizes (number of elements) should be $O(\log n)$.

comment Prove (without quoting any theorems) that polynomials on [0,1] are continous
I don't understand the point of the first question. Shouldn't you replace $P([0, 1])$ by $C^0[0, 1]$ in this question? You can then combine both questions to show the desired result. (What your version of the first question asks you to prove is true but I fail to see where you will need to use it.)

comment Width of a product of chains
Thanks a lot for this detailed answer! Is this new, or are those results from an existing source?
