Morphocompletion for #4280 ⟨a, b | abaabbbba=ab⟩

Solved by morph:5/0. (See Morphocompletion.)

Step 1

Checking up to 20 rules for overlaps.

Rewriting system is not complete: rulesLimit

Collecting factors up to length 8, frequency 7:

Length 2:	[2/0] bb, [2/1] ab, [2/2] aa, [2/3] ba
Length 3:	[3/0] bbb, [3/1] abb, [3/2] aaa, [3/3] aba, [3/4] baa, [3/5] bba, [3/6] bab
Length 4:	[4/0] bbbb, [4/1] abbb, [4/2] baaa, [4/3] bbba, [4/4] abaa, [4/5] abab, [4/6] bbaa
Length 5:	[5/0] abbbb, [5/1] bbbbb, [5/2] bbaaa, [5/3] bbbba, [5/4] ababb, [5/5] bbbaa, [5/6] abaab
Length 6:	[6/0] abbbbb, [6/1] bbbaaa, [6/2] bbbbba, [6/3] babbbb, [6/4] aabbbb, [6/5] ababbb, [6/6] bbbbaa

Considering [length 5 / frequency 0] abbbb=c.

Reduction order:
- Left-to-right recursive path with deg(a) = deg(c) = 0, a < c; deg(b) = 1
Auxiliary generators:
1. abbbb=c
