#5775 ⟨a, b, c | aa=b, ccc=cc⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 8
- Isomorphic to ℕ(3 = 2) ∗ ℕ
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by c is not injective:
-
c ⋅ c2 = c2 and c ⋅ c = c2, however c2 ≠ c
- Not right cancellative, because right multiplication by c is not injective:
-
c2 ⋅ c = c2 and c ⋅ c = c2, however c2 ≠ c
- Reduction order:
- Left-to-right recursive path with deg(a) = deg(c) = 0, a < c; deg(b) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
# abc:aa=b,ccc=cc ac/b - -
ccc=cc
b=aa
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
