Palindrome Conjecture Tester

This is a website to test the Palindrome Conjecture, which can be stated as follows:

If you take any number and add it to its inverse (digits reversed), after repeating the process with the result a finite number of times, will it eventually become a palindrome?

If you take any number and add it to its inverse (digits reversed), after repeating the process with the result a finite number of times, will it eventually become a palindrome?

Enter a range of numbers to test.

You can test one number by setting both fields to the same value.

Choose a maximum number of times to check whether a number forms a palindrome.

Lower iteration values can result in less accurate answers, but prevent numbers that don't form palindromes from freezing your computer.
