Subject: Iterate through Array?

I've been messing around with generating all possible combinations of a 
set of letters, (Ala, a 6 letter set would start enumerating at "aaaaaa" 
then move on to "aaaaab" so on and so forth, all the way down to 
"zzzzz") by iterating through an array using slice() , Which is a pretty 
good implementation for small tasks, But suppose I wanted to generate 
larger sets, Is there a more efficient implementation than say

     a=0
     b=0
     c=0
     d=0
     e=0
     f=0
     z = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", 
"m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"]

slice = z.slice(a) + z.slice(b) + z.slice(c) + z.slice(d) + z.slice(e) + 
z.slice(f)

if...
else.... [Incrementing]

     puts slice

Thank you in advance
