### Has there been any progress on Conway's and Soifer's shortest paper?

Jineon Baek and Seewoo Lee recently posted to the arXiv a paper claiming to prove the conjecture in the case that every small triangle in the cover has edges parallel to the large triangle. (The ...

### Conjecture: Given any five points, we can always draw a pair of non-intersecting circles whose diameter endpoints are four of those points

A counterexample is given by the following five points: (0,0),(1,0), \Big(-\frac{64867}{77629},\frac{3389}{60094}\Big), \Big(\frac{5981}{56176},\frac{32211}{34172}\Big), \Big(\frac{5925}{117812},-\...
