Talk:Countable Union of Countable Sets is Countable/Informal Proof

Unless I'm missing something, Countable Union of Countable Sets is Countable/Proof 1 is basically, if not exactly, a formalized version of this argument. That's the reason that I replaced this argument with that one. Comments? --abcxyz (talk) 17:00, 14 December 2012 (UTC)


 * You appear to be right. In fact, gave this argument, but I added the reference to Proof 1. That's how close they are. Maybe the only merit this has lies in an "informal proof" section. --Lord_Farin (talk) 17:03, 14 December 2012 (UTC)


 * You are completely correct. But why is this a problem? --prime mover (talk) 19:44, 14 December 2012 (UTC)
