Combinations


Hello everyone,

Does Mathematica have a built-in function that will generate a simple 
list all possible combinations of a list of strings?  For example, 
{a,b,c}, where the elements are strings, should give 3x3=27 triplets of 
"aaa", "aba", etc.

I tried

In[4]:=Outer[{a,b,c},{a,b,c},{a,b,c}]

but I get

{{{a, b, c}[a, a], {a, b, c}[a, b], {
     a, b, c}[a, c]}, {{a, b, c}[b, a], {a, b, c}[b, b], {a, b,
       c}[b, c]}, {{a, b, c}[c, a], {a, b, c}[c, b], {a, b, c}[c, c]}}

which is going to be difficult to match with my data using BinCounts 
and the like.

	Regards,

		Greg
