#8061 ⟨a, b | aaa=1, abab=bbb⟩
Contents
- Properties
- Rewriting system
- 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 ⋅ b10 = b5 and b ⋅ b4 = b5, however b10 ≠ b4
- Not right cancellative, because right multiplication by b is not injective:
-
aba ⋅ b = b3 and b2 ⋅ b = b3, however aba ≠ b2
- Reduction order:
- Left-to-right recursive path with deg(b) = 0; deg(a) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
