My son downloaded a program from winsite called Maxhit, and says when he asks it to predict sets of numbers, in a 100 number set he usually matches at least one set of five and a few sets of four and alot of three matches. His problem is that he has to go through the list manually. He was wondering if anyone knows of a program that he could import the lists to and have it check for repeating triples or quads. He asked me if a spreadsheet program could do this, but since most 4th graders probably know more about spreadsheets than I do, I told him I'd go here and ask the experts. I'm babysitting for him for the weekend, so I'll play with the program and see if I can figure it out.
