Re: unordered sets of N elements

japhy,
Here is the mathematical formula with a little help from google.

(N+5) (N+4) (N+3) (N+2) (N+1) / 120
[download]

If I were solving the problem using code and I couldn't figure out how to use one of those nifty CPAN modules, I would do it the inefficient way (sort, join, use a hash).

Cheers - L~R

Or, to take it to any number of sides: `k-1 ----- \| \| (N+i) i=1 ------------- (k-1)!` [download] Where N is the number of dice and k is the number of sides. The Pi is like Sigma, but for multiplication instead of addition. ------ We are the carpenters and bricklayers of the Information Age.

Wow. That's amazing. Thanks for finding that link for me. I hadn't used "dice" in my googling, and never found anything remotely close to what I needed. _____________________________________________________ Jeff `japhy` Pinyan, P.L., P.M., P.O.D, X.S.: Perl, regex, and `perl` hacker How can we ever be the sold short or the cheated, we who for every service have long ago been overpaid? ~~ Meister Eckhart	[reply]
