Math Is Fun Forum

Good day ~

I see there are other answers to this questions like this, but as far as I saw not for exactly what I am seeking.

Networking event: The goal is for each person to meet as many people as possible;
They may not repeat tables within day one nor may they repeat within day two - I know this is possible. However, they do not want the attendees to see the same people at the tables over the entire two day event = 7 rotations. Would you tell me if this is possible and share the breakdown? I have done it with a randomize function once and a pivot table...but both times table guests were repeated.

This is the breakdown...
We anticipate 30 participants; 5 tables (6 at a table)

Day One:
Must have three rotations - they may never repeat the same table twice (on this day) nor do they want them to see the same people at a table (however I think with a group of 30 this may be impossible...?)

Day Two:
Must have four rotations - they may never repeat the same table twice (on this day) nor do they want them to see the same people at a table.

Looking forward to your expert advise.
Thank you.
