#3461 ⟨a, b | aaabababaa=a⟩
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 c is not injective:
-
c ⋅ ba3c = c and c ⋅ 1 = c, however ba3c ≠ 1
- Not right cancellative, because right multiplication by c is not injective:
-
cba3 ⋅ c = c and 1 ⋅ c = c, however cba3 ≠ 1
- Auxiliary generators:
- c = ababa
- Reduction order:
- Left-to-right recursive path with deg(c) = 0; deg(b) = deg(a) = 1, b < a
- Certificate: derivations of all rewriting rules from the defining relations.
- Morphocompletion: how the auxiliary generators were found.
