Hello, ice, thanks for see the post, it is so. Do 01-58 pairs
*Gave a list of 1653 pairs, only along these pairs
*Are couples with repeated digits example
*01,20 ..... 12 32
*And it pairs without repetition of digits = ex = 12.38 .. no repetition of digits
These double that must separate the list are 4 digits (dig and the last number) = distinct = 1,2,3,8 are. Should give a 800duplas without repetition of digits
*Another example of this can = 01.23
15.56 = can not. Delete digtio has 5 repeated, delete, have to use this filter because in 88% giving this pattern of such double
