@dudeney_puzzles One way to solve this could be to consider the men as non-identity elements of \( \left( \frac{\mathbb{Z}}{2\mathbb{Z}} \right)^4 \) . Then you could consider how many subgroups isomorphic to \( \left( \frac{\mathbb{Z}}{2\mathbb{Z}} \right)^2 \) can one find?

Can you suggest a nice 10-20 km trail in Switzerland with a scenic view?

@hexbienium Sorry, still learning Latex usage.

@hexbienium So I was just wondering, \( O(N) )\ is just by arranging the points in a line, right?
