You should already know if the question I posted contains word "chirality", something must be wrong
More seriously, question was intentionally lousy. To be honest I didn't even know how lousy it is - that is, I knew of two possible reasons why the answer is not unique (BTW: one was not yet mentioned in the thread, although I was contacted by PM by fledarmus), could be there are even more problems with the question. But I wanted to stir a discussion and I know from experience best way to catch your attention is to post some kind of nonsense
I wanted to ask you about Problem of the Week - do you think it makes sense to continue (I do plan to), do you have any ideas about how to make it more interesting, do you know questions that you think will fit, or perhaps you just have an idea that you think could be made into an interesting question with some work?
