3X+1 (only 54 blocks) mathematicians have been trying to figure this formula out for decades and have brute tested numbers all the way up to 2^68 (295,147,905,179,352,825,856) the problem is "does any number (whole positive #) not go into the 4 2 1 loop?" rules of 3x+1 if the #1 is odd #2 will be ((#1)*3)+1 if the #1 is even #2 will be (#1)/2 all numbers so far go to 4-> 2-> 1->4 ... for example 6-> 3-> 10-> 5-> 16-> 8-> 4-> 2-> 1-> 4
