Properties

Presentation has sum-of-sides 10
Infinite cancellative non-commutative monoid
Submonoid of enveloping group: ⟨a, b | aaabbab^-1a^-1bb⟩

Embedding: φ(a) = b, φ(b) = a

Rewriting system

Format:	Pretty Plain
Word to reduce:
	Tips: Lowercase letters stand for generators. Spaces are ignored. Numbers repeat the previous letter, e.g. `b90`.
Reduction strategy:	Leftmost Rightmost
Path to normal form:	1 1

Auxiliary generators:
1. c = bbaab
Reduction order:
- Right-to-left recursive path with deg(a) = deg(c) = 0, a < c; deg(b) = 1
Certificate: derivations of all rewriting rules from the defining relations.
Morphocompletion: how the auxiliary generators were found.

#	Rule	Proof
1.	(a²c²a²(ac²)³a³c²a)²c² ⇒ ca	[11]
2.	ba ⇒ a²c²ab	[7]
3.	bc ⇒ c²ab	[6]
4.	(a²c²a²(ac²)³a³c²a)²b³ ⇒ c	[12]

# ab:aabbbaab=ba reversed:ac/b bbaab=c morph:5/0
