#821 ⟨a, b | aabbbaab=a⟩

Quick links

Presentation has sum-of-sides 9
Infinite non-cancellative non-commutative monoid
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ ab³a²b = a and a ⋅ 1 = a, however ab³a²b ≠ 1
Enveloping group: ⟨a, b | aabab^-1b^-1⟩

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=a ba
aabbba=abbaab
aaabab=abaaba
abaabab=abbaaba
abbaabab=a
