Is it just me? I really hate how the problem is phrased on that page. Here's the original:
"33 horsemen are riding in the same direction along a circular road. Their speeds are constant and pairwise distinct. There is a single point on the road where the horsemen can pass one another. Can they ride in this fashion for an arbitrarily long time?"
Here's a quick take on how I would rephrase it:
"33 horsemen are riding in the same direction along a circular road. There is just a single point on the road where any number of horsemen can pass each another; everywhere else, a faster rider coming up behind a slower rider will be stuck and have to slow down. Is there a set of pairwise distinct speeds the horsemen can ride at such that the riders can all start at the passing point, ride constantly at their given speed for an arbitrarily long time, and only meet each other at the passing point (thus never having to change speed)?"
