Potential consecutive triplet that merge before 1 but not continuously

To show why continuous merging is part of the defintion of a tuple, here is the example of 10316-10318.

1. It is a consecutive group of the same length that merges long before 1 (over 100 iterations).

2. 10316-10317 is a final pair (orange-yellow) that merges in three itarations.

3. The second merge shows unusual patterns: the larger
