@ТymaGaidash I am surprised that this is possible at all. I always thought the question has to be undeleted first before it can be reopened. Apparently I was wrong.
To prove that the Collatz conjecture is false, one does not need to find a solution. One only needs to prove that the probability of a sequence never returning to '1' is greater than zero. Each division by 2 has a probability of 0.5 that the result will be an odd number. No matter how many odd...
