Getting all the elements from an array that have the same value

hey, i am not able to solve for something.

the image you are seeing above, i want to create specific columns like 1-vs-1, pool of 5, etc., based on the array in leagues played. leagues played is a lookup column based on the bets relation column. please help.

So you want a unique array?

Try this “Unique Elements” column on your array, and then use a “Joined List” column to join the text together for display purposes, if you need to do so.
