Hi Bernard, I did google "excel permutations combinations" and went
through all the 'Combinations' previous posts
but unfortunately could not find any code that does anything like the
code Mike has written...

Mike, that code is fantastic! thankyou very much, there is NO way I
could have written it.
you are right, I thought there would be 252 combo's but I was wrong.

Q. Where in the code would I adjust it to generate 4's and the 3's
I am not pretending to understand your code, because I don't.
Is the alteration something to do with the fourthno and fifthno?

Once again...cheers

Ste
