My key-rings are metal circles of diameter about two inches. They are all linked together in a strange jumble, so that try as I might, I can’t tell any pair from any other pair.

However, I can tell some triple from other triples, even though I’ve never been able to distinguish left from right. What are the possible numbers of key-rings in this jumble?

The above is like a riddle I suppose? A math riddle I guess. I'm at this pi day party and they gave me this math riddle. Would anyone like to help me solve this? I have till midnight tonight and it's 4:22PM over here.

If you don't know how to solve this, it's okay. It's not required schoolwork, it's optional and its not even schoolwork, it's for a pi day party.
