#1979 ⟨a, b | aababbba=ba⟩

Quick links

Presentation has sum-of-sides 10
Infinite non-cancellative non-commutative monoid
Not right cancellative, because right multiplication by a is not injective:
- a²bab³ ⋅ a = ba and b ⋅ a = ba, however a²bab³ ≠ b
Enveloping group: ⟨a, b | aabab^-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
