# Maximum possible 10 character string combinations from 36 unique characters

Posted on 2016-09-30

I am trying to determine what is the maximum number of 10 character word string combinations that can be created using 36 unique characters. For example, let's say that you use the English alphabet, all lowercase letters, a-z, and all the Arabic numerals, 0-9. You would end up with 36 unique characters to work with:

abcdefghijklmnopqrstuvwxyz0123456789

With these 36 characters, how many unique 10 character strings can be created? What would be the math formula that would be used to determine the answer to this question?

You could start at:

aaaaaaaaaa

then iterate to.... aaaaaaaaa1, then aaaaaaaaa2, etc...

eventually, the last possible 10 character string would be... 9999999999

If you tallied up all the possible combinations, how many would there be?

Would it 10 to the 36th power?
