comment Pigeonhole principle question confusion
@DJC Thanks, but I don't really see any application of that... anywhere. So there can be no injection from the set of natural numbers to the set of reals.. so?

comment $n$ lines cannot divide a plane region into $x$ regions, finding $x$ for $n$
@Qiaochu That's probably because I posted a comment before I decided flagging it would be better. Sivaram did the edit before any of the mods.

comment $n$ lines cannot divide a plane region into $x$ regions, finding $x$ for $n$
@Qiaochu I had edited the question before appealing. I did not see the changes happening. Please see edit history. math.stackexchange.com/revisions/… If I do a rollback, the curly brackets will disappear and the $x=5$ will appear on top of the post instead of the last line.I dont want to spoil Sivaram's formatting, but if you can make a rollback and then reverse it, then please do. If my browser was really the problem, then I would apologize for the unnecessary flag.
