Challenge #247: Pairing Partners

[BS_THE_ANALYST]

Couldn't figure out the algorithm myself. Used the hint with the circle method. Makes complete sense. Just an iterative macro after that!

My solution

Well, I'm stuck. I read the hint and watched a video on youtube. I've tried seemingly a 100 versions of my macro and I get close - but no cigar. After too many hours on this one, this is my best shot. I have dupes in my output. So don't call me to organize lunch pairings!
