I'm going to math gurus for this one. Does anyone have a group based table seating chart for speed networking event so that everyone rotates around and doesn't overlap or there is very very little overlap. Right now we have about 60 people, there is always one table leader that never moves. the rest of the table could be four, six, eight people extra. I can't find a anywhere or an excel file that I can just plug in numbers and have it tell me the rotation matrix.

Thanks in advance!

Hi QuestioningMind;

It is not necessarily a rotation matrix.

They are related to the "Progressive dinner problem." I have worked on three of them here. Yours has a twist to it and is rather large in size.

Bobby, one of your progressive dinner rotations popped up in my Google search and what led me to post on here. I've found one company that apparently offers the service for you, but they want to handle all of it, and all we need to be able to do is plop in the total number of participants, total tables and it gives us a rotation plan similar to this...

Table
1 2 3 4 5 6 7 8 9 10 11 12 Person 1

Obviously the first person is the easiest as they go straight through however many tables. Historically we have had 90 and up on these with either 14 or 15 tables, you rotated through 12 table and had a chart for that many people. You don't see everyone, but it got most of them, a few people you would see twice, but as long as that was limited, it is okay. The numbers are down this year and we can't figure out how to re-work the numbers.

Hi;

So, you actually had a chart for 90, that is impressive. So would a progressive dinner structure be suitable for you?

QuestioningMind · 2011-08-01 07:55:56

We had a chart for 98 with 14 tables and 14 table leaders running on a 12 table rotation, not all 14. Not sure where they got it originally from. This time we are looking at 62 so far so are guessing there will be 70 total.

Hi;

I have a setup for 60. Not all numbers have a nice answer. Will try for a 70.

Oh wait, the last thing I want is to solve this one only to find out 70 is not what you want. Do you have a definite number?
