Linked Rings (Posted on 2004-05-29) Difficulty: 2 of 5
Three rings (planar circles) are "linked" together, but you'll notice that none is directly linked with another.
  • The red ring is "behind" the yellow.
  • The yellow ring is "behind" the blue.
  • The blue ring is "behind" the red.
Still, while none is intertwined with another, it is impossible to pull them apart.

Is this a paradox?

Can this really be built?

My Guess | Comment 1 of 19

My guess is that the whole structure is invalid because it violates the transitive property (if there's no intertwining). If blue is behind red and red is behind yellow, blue should be behind yellow by the transitive property.

This seems a little too simple. There might be something I'm missing.
