## Create permutations [UDF]

Maximum Number Allowed is 4 digit and the number is from 0 to 9.

After I fill in the number i want it to automatic permutate the numbers and list in details, example if i key in 1234 and the list will be:

1234, 1243, 1423, 4123, 1324, 1342, 1432, 4132, 3124, 3142, 3412, 4312, 2134, 2143, 2413, 4213, 2314, 2341, 2431, 4231, 3214, 3241, 3421, 4321.

#### Answer:

This udf creates permutations from a text string. You can also choose how many letters in each permutation.

i am trying / looking for a way to write in-excel 2007, 20 numbers out of 1 to 45 like Australian lotto ,there is a site that you probaly know...will give 4 out of 4 numbers while seleecting up to 12 picked.is the a way I can show 45 numbers ie 1 to 45, then use hlookup, and get it to show the cells for the first 6 out of the 45, and so on..

thanks Bert

bert

Can you explain in greater detail?

looks like there's a syntax error with the line starting If rng(r - 1, c - 1) < rng(r - 1, c) Then..... unable to execute the code

Thanks for making your code accessible to everyone. Super helpful!

Thank you for telling me, I hope it works now.

In case it is not working, there is a file you can download.

Hi Oscar,

Can you give a file that i can download for this code?
