196
the answer for puzzle #114
The five clues
- A three-digit perfect square.
- The seed of the most famous Lychrel search.
- The square of a two-digit number.
- The square of fourteen.
- The smallest Lychrel candidate: repeatedly reversing and adding has never yielded a palindrome.
Backstory
196 = 14² is the most famous suspected Lychrel candidate: iteratively add a number to its digit reversal (196 + 691 = 887, 887 + 788 = 1675, ...) and, after over a billion iterations, no palindrome has appeared. No proof exists that 196 is Lychrel — nor that it is not.
