Hmmm... It's quite clear that WM doesn't have ANY fun with math, I'd

Most cranks don't to any (real) math, they just "criticizes" (sort of)
things they don't really understand.

Here's and interesting problem to code up.  The input is a finite array
of n pairs of strings, so there are 2n strings in all.  They are often
thought of as strings on the top and bottom of a collection of tiles or
dominos, but that just help visualise the problem.  An example with n=3
might be
   aa     bb    abb
   aab    ba     b

Would that work?

If I understand you, yes.  It's a simple case where the tiles, used once
in some order make a solution.  In most cases is will be much harder to
determine if there is a solution.

Does each string need to be unique?

No.
