#2000 ⟨a, b | aabbbaab=aa⟩

Quick links

Presentation has sum-of-sides 10
Infinite non-cancellative non-commutative monoid
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ ab³a²b = a² and a ⋅ a = a², however ab³a²b ≠ a
Enveloping group: ⟨a, b | aaaabb⟩

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

# ab:aabbbaab=aa ba
aaaab=aabaa
