-- EDIT INSTRUCTIONS -- Press up arrow. Then, press the down arrow. -- --- --- --- --- --- -- The conjecture: Take any natural number n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. Repeat the process (which has been called "Half Or Triple Plus One") indefinitely. The conjecture is that no matter what number you start with, you will always eventually reach 1. ------------ The Collatz conjecture has not been demonstrated yet. If you've tried a number that does not confirm it, write this number in comment, please! It is a conjecture in mathematics named after Lothar Collatz, who first proposed it in 1937. It is also known by the Syracuse problem:
I have made scripts that go through the numbers and get the maximum-levels out of the series, (as before), then recording the values in a list ('maxxes'). The script then, (after 'down arrow'), takes the unique answers from out of the 'maxxes' list and says when those values first appear (in 'source'::'uniques').
