29 numbers group is the same:
23,33,2,11,26,9,31,34,5,18,6,7,16,19,17,21,28
15,35,23,8,10,12,20,24,30,32,36,29,13
Leftover group is the same: 25,22,1,4,19,27,14
10 numbers: 15,25,22,1,4,20,19,27,35,14. ( This is just whimsy, I am experimenting)
If there will be one or two single numbers, then they are not 8 or 9, which means look for them among 1,2,3,4,5,6,7. I will try to go farther and try to predict that single numbers, if they come up, will be among 3,4 ( well, this sentence sounds risky. I am scared to lead you in a wrong direction). If there are more single numbers then two, it can be any single-digit number.
It seems that combination will fall back to having some single numbers. I have suspicion that double-digit numbers will be all even. Will see if it is so. Things or new observations oftentimes happen for the first time, where I don't have set system of conclusions. I just have to wait and see.
