There are significant differences in speed between 5.5 and 6.6. Not so much in deriving the permutations as in displaying the results in a field.

I guess that's true. The values in millisecs that I have posted are taken without putting the result into a field. Just the plain calculation of the permutations.
But I think it quite a pity (to put it mildly)  that LC 6.xx is so much slower thank 5.5.
