@bmehmet hey David I have another filter idea with pairs. Very similar to pairsums. I will just keep the list of pairs in boxed form since I don't wanna make post too long. Its called the line/width pairs. line/width is the difference between the biggest number and smallest number in the number combination. For example number 518 has a line/width of 7. Biggest number (8) minis smallest number (1) = 7. Can do that with pairs. It would set up just like pair sums. So 518 would be front pair 2,2, split pair 2,1, and back pair 1,1. (2,2/2,1/1,1)
