I'm afraid I don't know what closures are yet. Are you perchance referring to how the reals can be "constructed" from the rationals? If so, yes, that would be a very interesting "property" to lose: constructibility from a countable set.

I agree. I'm finding it hard to put my question into words precisely enough. But a description of what this $\mathbb{R}$-countability is would be interesting.

This seems like something that answers my question, but it assumes a little more knowledge about cardinals than what I possess at the moment. Could you please expand on the parts of your answer that relate to "large cardinals", please?

@Paul, thanks for your answer, but this does not answer my question. I apologize for not having stated it clearly enough earlier.

You are right. I'll update the question with some details.

@ClaudeLeibovici Not to be rude or condescending at all, but the asker's approach to the problem makes me doubt it was intended to be solved in any way apart from simple calculation.

comment My answer to this combi problem doesn't match the answer in the book (Problem-Solving Strategies)
Indeed, I have. I don't think I should write Olympiad books, either . . .
