Talk:Round-robin
From Wikipedia, the free encyclopedia
How do you do round robin gift exchange with even numbers without re-gifting to the same person....?
1234, 4321, 1<>3 / 2<>4 1234, 4321, 1<>3 / 2<>4
5 people works fine... 12345, 54321, 135241, 14253, repeat
I think six has the same issue and I suspect 8, 10, etc.
Am I incorrect? I'm not a mathematician, I was just trying to figure out a rotation for my family this year... and am stumped.
