list question... unique values in all possible unique spots

[ToshiBoy]

Thank you for all your responses. I've tried the permutations road
(thank you to all those of you who have suggested it) and it takes %*&
%^ long :-) As expected. I've solved it a different way, which runs
through the 26 spots by just adding one at a time if available. Still
takes a long time, but not as long as the permutation. That said,the
permutation works great for other projects.
