How to list all possible 4-digit combinations of 0 to 9?
In Excel, you can use below formula to list all possible 4 digits combinations of number 0 to 9. Select a blank cell and type this formula =TEXT (ROW (A1)-1,"0000") into it, and press Enter key, then drag the autofill handle down until all the 4 digits combinations are listing.
What are some combinations of numbers with repetition?
Some of the combinations include {0,0,0,0}, {9,9,9,9} and all arrangements between. Since the order of digits matters ( {0,0,0,1} is not equal to {0,0,1,0}) and repetition is allowed (each digit can be in any of the four positions), the arrangements are called “permutations with repetition.”

1. Permutations with repetition
I explained in my last post that phone numbers are permutations because the order is important. But phone numbers may also contain duplicate numbers or repeated numbers like 11 234, here number 1 is repeated. A digit in a phone number has 10 different values, 0 to 9. A five digit phone number has 10x10x10x10x10 or 10^5 equals 100 000 permutations.
2. Constructing a permutations array with binary values
Excelxor showed us how to build a permutations array using only excel functions, in one of his blog posts.
4. Permutations without repetition
Imagine constructing an anagram of a word " police". You are allowed to rearrange the letters but you can´t repeat a letter. See picture to the right.
