For those who are interested in this method, copy and paste it into your notebook, then use the finder "apple + F" for Mac, and "ctrl + F" for PC. for quick find of the number, then mark it off or moved it to another notebook page.
It may take many attemps to get a hit, remember it is an extremely cold number for a reason. Covering the possible straights for one number can be worth the chase. Each number have 6 straight numbers; ex. 123 = 123, 132, 213, 231, 312, 321.
