If you put a sequence of Rubik’s cube moves into this thing it’ll spit out the number of times that sequence needs to be repeated in order for you to put the cube back in the state that it started in. So, for instance, “F”, will output 4, because after four twists of the forward face of the cube it’ll all be back where it started. I thought I’d keep track of all the sequences tested before I really realized that there’s probably a fairly low (i.e finite) possible maximum, and that I’ve reached it. But that’s why you can input your name and hometown — in case you set the record.
