#5866 ⟨a, b | ababab=aabab⟩

Quick links

Presentation has sum-of-sides 11
Infinite non-cancellative non-commutative monoid
Not left cancellative, because left multiplication by a is not injective:
- a ⋅ b(ab)² = a(ab)² and a ⋅ (ab)² = a(ab)², however b(ab)² ≠ (ab)²
Not right cancellative, because right multiplication by b is not injective:
- a(ba)² ⋅ b = a(ab)² and a²ba ⋅ b = a(ab)², however a(ba)² ≠ a²ba
Enveloping group is isomorphic to ℤ

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 = aabab
Reduction order:
- Left-to-right recursive path with deg(b) = 0; deg(c) = deg(a) = 1, c < a
Certificate: derivations of all rewriting rules from the defining relations.
