Term size (digits) across the sequence — How the sequence develops - decimal digits of each term vs iteration.

n	Status	Digits	Term	Factorization
0	Fully factored	3	676	2²×13²
1	Fully factored	3	694	2×347
↳	Merges Joins the sequence of 220 (at index 1 of that sequence) - the terms below continue there.
2	Fully factored	4	1371	3×457
3	Fully factored	4	1993	1993
↳	Terminates The sequence reaches a prime and terminates.
