#5286 ⟨a, b | aba=bb, abbb=a⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 10
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ b3 = a and a ⋅ 1 = a, however b3 ≠ 1
- Not right cancellative, because right multiplication by a is not injective:
-
b3 ⋅ a = a and 1 ⋅ a = a, however b3 ≠ 1
- Reduction order:
- Left-to-right shortlex with a < b
- Certificate: derivations of all rewriting rules from the defining relations.
