#20297 ⟨a, b | aba=b, abbb=bab⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 11
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by b is not injective:
-
b ⋅ b2 = b2 and b ⋅ b = b2, however b2 ≠ b
- Not right cancellative, because right multiplication by b is not injective:
-
b2 ⋅ b = b2 and b ⋅ b = b2, however b2 ≠ b
- Reduction order:
- Left-to-right shortlex with a < b
- Certificate: derivations of all rewriting rules from the defining relations.
