#27657 ⟨a, b | aa=1, ababbb=bbb⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 11
- Infinite non-cancellative non-commutative monoid
- Element ba has infinite order
- Not left cancellative, because left multiplication by b is not injective:
-
b ⋅ b3 = b3 and b ⋅ b2 = b3, however b3 ≠ b2
- Not right cancellative, because right multiplication by b is not injective:
-
b3 ⋅ b = b3 and b2 ⋅ b = b3, however b3 ≠ b2
- Reduction order:
- Left-to-right shortlex with a < b
- Certificate: derivations of all rewriting rules from the defining relations.
