#7796 ⟨a, b | aaa=1, abbab=bb⟩
Contents
- Properties
- Rewriting system
- Anti-isomorphic instances
- Sum of relation sides is 10
- Infinite non-cancellative non-commutative monoid
- Element ba2 has infinite order
- Not left cancellative, because left multiplication by b is not injective:
-
b ⋅ b8 = b3 and b ⋅ b2 = b3, however b8 ≠ b2
- Not right cancellative, because right multiplication by b is not injective:
-
ab2a ⋅ b = b2 and b ⋅ b = b2, however ab2a ≠ b
- Reduction order:
- Left-to-right recursive path with deg(b) = 0; deg(a) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
