Have just discovered that the last 10 draws in our NZ Lottery have not appeared in any consecutive pair of previous draws - the 11th failed once. If there were no repeat numbers in any pair of consecutive draws that would be 1.8 million combinations (2080 draws) which I would be happy to eliminate. That's 12 boxed numbers (928 lines) x 2080 draws. Is there an easy way to do this? I can only see using number groups as a way to do it - can I have 2080 number groups? Repeat numbers will reduce that number but it will still be a very large set of combination to remove.
Edit: Also see that the non-appearance of any 4 numbers appearing in recent consecutive pairs of draws is worth looking at.
