#10023 ⟨a, b | aa=1, abbbba=bb⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 10
- Infinite non-cancellative non-commutative monoid
- Element ba has infinite order
- Not left cancellative, because left multiplication by b is not injective:
-
b ⋅ b7 = b2 and b ⋅ b = b2, however b7 ≠ b
- Not right cancellative, because right multiplication by b is not injective:
-
b7 ⋅ b = b2 and b ⋅ b = b2, however b7 ≠ 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.
