If the caretaker remembers 5 eggs which he might have swapped two of them,

(5c2) or 10 possible combinations,how he could find the pair with 2 trials?

Spoiler for for 5 eggs, it's easy with digital scale

I started working out a similar solution for 10, but didn't have enough time to finish it yet. I'm trying to do it in 3 weighings using a digital scale, but so far, looks like it will require 4. Maybe a combination of digital/balance could be optimal. Is it allowed?

I think you should mark this as solved. There is no way to place 6 points on a surface in a way that the minimum distance between any 2 points was m and the maximum distance between any 2 points was m*sqrt(3).
