Editing Lychrel number (section)

== Threads, seed and kin numbers ==
The term '''thread''', coined by Jason Doucette, refers to the [[sequence]] of numbers that may or may not lead to a palindrome through the reverse and add process. Any given '''seed''' and its associated '''kin''' numbers will converge on the same thread. The thread does not include the original '''seed''' or '''kin''' number, but only the numbers that are common to both, after they converge.

'''Seed''' numbers are a [[subset]] of Lychrel numbers, that is the smallest number of each non palindrome producing thread. A seed number may be a palindrome itself. The first three examples are shown in bold in the list above.

'''Kin''' numbers are a subset of Lychrel numbers, that include all numbers of a thread, except the seed, or any number that will converge on a given thread after a single iteration. This term was introduced by [[Koji Yamashita]] in 1997.
