Considering the numbers:
01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25
How do I generate lists of 15 items (numbers quoted above), and they must have at least 2 items of difference between them. For example:
01,02,03,04,05,06,07,08,09,10,11,12,13,14,15
01,02,03,04,05,06,07,08,09,10,11,12,13,17,18
01,02,03,04,05,06,07,08,09,10,11,12,13,20,22
01,02,03,04,05,06,07,08,09,10,11,12,13,21,25
Please note in the end, I have just changed the last 2 items of each list, they are unique, they do not exist in the other lists. How do you do this in practice, and the 2 difference items can be in any position?
