Using the dynamic array functions, I created a formula that will return permutations, with or without repetitions, based on a range of values you select. I used the lambda function to turn it into an easy-to-use formula.
Just wanted to share because I think it's cool, permutations come up a lot, and I'd like to see what everyone thinks. I'm sure that this formula could be optimized or shortened.
Name Manager Lambda function "PermutX"
