A rotating schedule for 9 individuals

Quandaries & Queries

Question from Josh:

I need to set up a rotating schedule for 9 individuals.
The individuals will be pairing each week in groups of two.
Thus, every week there will be 4 groups of two individuals and one individual not paired with anyone (i.e. a "bye week").
The rotating schedule should not repeat any pairing and it will continue until each individual has been paired with every other individual once.
Thank you

Josh,

Try this:

Week 1: 1, 8; 2, 7; 3, 6; 4, 5; OUT 9
Week 2: 2, 9; 3, 8; 4, 7; 5, 6; OUT 1
Week 3: 3, 1; 4, 9; 5, 8; 6, 7; OUT 2

The next week is obtained from the current one by adding one to each (player) number, and wrapping 9 +1 around to 1 like an odometer.

Hope this helps.
