July 29, 2009

It looks like there will be a new polymath project soon here is a thread discusing the problem:

Here is a wiki for the above problem:

There are also some related items:

Here are some Polymath proposals:

Proposed Polymath3

July 21, 2009

There is a discussion about a proposed polymath devoted to the Hirsch conjecture. Here is the url:

Let me update this: Here is a new discussion thread on this topic:

A mini-polymath project

There is a mini-polymath project based on an International Mathematical Olympiad problem at:

I want to update this. There is a new thread for this at the following url:

A new result in the Polymath1 paper

July 11, 2009

We have just added a new result. It is the following: The maximum number of points that a six dimensional cube of side three can have without forming a geometric line is 353. We have a 353 point set without a geometric line and a proof that all sets with 354 or more sets must contain a line.

Let me update this. There was a problem with the proof that was found on the 20th of July and fixed on the 25th. There is a new version of the paper with the proof fixed. Also the main page of the wiki has been changed to link to other polymath projects.
