Possible Lychrel number
A Lychrel number is a natural number which cannot form a palindromic number through the iterative process of repeatedly reversing its digits and adding the resulting numbers. 196 is the lowest number conjectured to be a Lychrel number in base 10; the process has been carried out for over billion iterations without finding a palindrome, but no one has ever proven that it will never produce one.
