Anyone see any holes in this proof?
Question:
>25 points are chosen inside a regular hexagon of side length 10 furlongs.
>Prove that some number of them are at most 5 furlongs apart, and state the number.
cited proof: http://arxiv.org/abs/1009.4322

>furlongs
P good bait op

it was just a quirk of the question. I copied it verbatim.
obviously the units dont matter

bump please

yep its an old one. it leaves the less space between circles and the perfect arrangement for circle arrays

The one niggling issue i am having is with an assumption of mine - that the points lie on the edge of the hexagon.
Its kinda obvious that that is the best way to fit the maximum number of points in the hexagon, but I cant figure out how to prove it.

easy. just tell them to either disprove it or fuck off :^)
