It states that repeating the sequence of operations described in the comic will eventually lead to the number 1. The description in the comic starts out accurate, then veers into the joke. |
− | + | The comic illustrates the sequence with a graph in which an arrow connects each number to its successor. For example, the number 22 is even, so the next number in the sequence is 22 ÷ 2 = 11, and there is an arrow from 22 to 11. On the other hand 11 is odd, so the next number is 3 × 11 + 1 = 34, and there is an arrow from 11 to 34. | |

+ | According to the title text, the person in the comic is obsessively writing out the graph by hand, and is so preoccupied with the task that he has stopped socializing with his friends. The person in the comic will be busy for a very long time, because the Collatz conjecture has been confirmed for all starting values up to 5 × 10<sup>18</sup>. | ||
+ | |||
+ | The ''Strong Collatz Conjecture'' in the title text is a humorous extension of the Collatz Conjecture. | ||
