A Lychrel number is a natural number that cannot form a palindrome through the iterative “Reverse-And-Add” process of repeatedly reversing its digits and adding the resulting numbers. This process is sometimes called the 196-algorithm, after the most famous number associated with the process.
In base ten, no Lychrel numbers have been yet proved to exist, but many, including 196, are suspected on heuristic grounds. The name “Lychrel” was coined by an American mathematician Wade Van Landingham as a rough anagram of Cheryl, his girlfriend’s first name.
In our project we will concentrate our efforts on:
(1) Proving that some numbers are indeed Lychrel
(2) Finding large Lychrel numbers in empirical search
(3) Deriving Lychrel numbers through application of certain algorithms
