random number generators

[waterballoon]

I'm trying to generate random batches of non-repeating numbers. Can't seem to find the right formula out there. They are combinations of 8 numbers from a larger selection depending on the group. Trying to write a UDF where I can use with any amount of numbers.

Any thoughts out there?

Thanks in advance.

This may be worth a look at?

It's actually a bit over the top for me to understand....

I'm curious to find if there is a combination of formulas I can plug into the cells to generate the numbers for me. I'm just expecting to get circular references...

At a stab, the below has numbers generated at random - someoen else may expand on this but the results I would filter and remove the first decimal place, then check if random, how many are you looking to generate>?

Note cell A8 I was testing.

What I'm trying to accomplish (maybe an explanation will help find a solution):

I have a different pools of players in the amounts of 15, 16, 17, 18, 9, 10, 11, 12, 13, 14.

I want to put them in groups of 8 (to play 4 vs 4) so that they play against/with someone different for the most part in every game and that they all play the same amount of games relatively.

Play a total of 12 games each. (3 a day for 4 days).

I already finished the pool for 8 players but it got so tedious that I decided to search another avenue. Also was supplied with a group of numbers generated for the 13 player pool (thanks for that). Just need to know how to do it!

Thanks!

Im still none the wiser, maybe someone else can assist from here. Good Luck.

Failing that, post a slecetion of your data to assist with the answer.
