I think you're right that it would be more work initially for the "all possibilites" hash. I'm no mathematician/statistican but I think there are more like 5! = 120 possibilities (and I certainly wouldn't want to build that hash by hand). Tilly, you're a mathematician. What are the correct number of possibilities?

Building the hash programmatically would be an interesting brain teaser.

Update: This was assuming string lengths of up to 5.

If the code and the comments disagree, then both are probably wrong. -- Norm Schryer
