:: Why is this even an issue? Regardless of whether or not 0 is tested, 0 is not a Lychrel number because 0+0 = 0 and 0 is a palindrome. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 18:01, 31 August 2015 (UTC)
== How can a Related number be a palindrome? ==
We're asked to list "Seeds or related numbers" that are palindromes.
How is it possible that a related number is palindromic?
Surely that would stop its seed from being a Lycrel number?
Could someone provide an e.g. and explanation (or rewrite the task objetive)?

: |Hi Tim, there is a version of the algorithm that does not produce palindromes, but the key is in this:
:: ''Notice that the check for a palindrome happens after an addition.''
: That example starts with the palindromic number 55 but the check comes later.

: 4994 is an example of a related number which is a palindrome. There are other examples. And like Paddy said, we only reject the seed if a sum was a decimal palindrome. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 13:18, 12 September 2015 (UTC)
