Here is my analysis/recheck on what was shared as I mentioned I would. I am using zero indexing and going by the order I seen the files posted.
-f7_5906_revisit_Kristan (files.zip) has 7324615 at 4836 and 4843
-THOM5906.V0005 has two duplicates: 5132467 at 1056 and 1063 & 7324615 at 4836 and 4843
-THOM5906.V0004 has no duplicates
-THOM5906.V0001 has no duplicates
-THOM5906.V0003 has one duplicate: 7324615 at 4836 and 4843
-THOM5906.V0002 has one duplicate: 5132467 at 1056 and 1063
This is what I meant when I said I had to recheck the last batch and didn't believe all of them had anything to note in regard to duplicated permutations.
I thank you again for sharing your findings as it gives me good data for my research. Keep up the good hunt!
