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
