Permutations of Characters Within a String
This program computes the number of unique permutations that can be made from a string of text characters.
Any text character repetitions are also taken properly into account.



Enter a String of Up to 80 Keyboard Symbols or Characters (Any letters ARE case sensitive).

For case INsensitive computations, simply ENTER ALL TEXT IN UPPERCASE Or ALL text in lowercase letters.

There should be no leading or trailing spaces in the string. They will be lost.
All spaces within the string are counted as characters.
