I’ve just opened the research thread for the mini-polymath3 project over at the polymath blog. I decided to use Q2 of this year’s IMO, in part to see how the polymath format copes with a geometric problem. (The full list of questions for this year is available here.)
This post will serve as the discussion thread of the project, intended to focus all the non-research aspects of the project such as organisational matters or commentary on the progress of the project. The third component of the project is the wiki page, which is intended to summarise the progress made so far on the problem.
